Pervaporation competes with conventional separation techniques, such as distillation and adsorption in organic liquid dehydration, removal or recovery of organic compounds from aqueous solutions, and separation of organic-organic mixtures. Pervaporation is a separation technique relying on the concentration gradient, often expressed as partial vapor pressures, across polymeric or polymer-composite membranes. Those membranes often exhibit a strong trade-off between permeability and selectivity of target compounds, making the search for alternative materials with advanced performance characteristics highly desirable. Metal–organic frameworks (MOFs), a sub-group of porous functionalised materials, have recently demonstrated potential to become a valuable building block in the fabrication of future high-performance pervaporation membranes. MOFs feature unique properties, such as molecular sieve effects, preferential adsorption to the target molecular compounds, and thermal and chemical stability, being suitable for direct applications in pervaporation separation of liquid mixtures. This paper comprehensively examines the current design strategies of MOF-based membranes in pervaporation. The main developments of MOF-based membranes in pervaporation are discussed and the performance of pervaporation processes using MOF-based membranes is also analysed. Furthermore, some perspectives for future development of MOF-based membranes in pervaporation are given.

Minimal cost per ton of captured CO2 and associated environmental impacts are considerable barriers for the industrial implementation of post-combustion CO2 capture. Aqueous solvents promoted with the enzyme carbonic anhydrase are a promising alternative to replace energy intensive and environmentally unfriendly amine-based solutions, which are currently benchmark solvents in CO2 absorption. However, using free enzyme in solution requires significant amounts of enzyme in addition to its possible denaturalization. Enzyme immobilization appears as a rational approach to develop a novel CO2 capture system using aqueous solvents. In the recent literature, efforts are focused on the development and characterization of different carriers and immobilization strategies to achieve good activity and stability compared to free enzyme in solution. In the laboratory and the industry, immobilized carbonic anhydrase have been already tested in a variety of configurations including packed columns, gas-liquid membrane contactors, dynamic devices and selective membranes. This article reviews the developments, opportunities and limitations found at laboratory scale as well as in the industry, and brings them together in order to identify the key challenges and perspectives in the industrial implementation of immobilized carbonic anhydrase for CO2 capture.

Ionic liquids have attracted the attention of the industry and research community as versatile solvents with unique properties, such as ionic conductivity, low volatility, high solubility of gases and vapors, thermal stability, and the possibility to combine anions and cations to yield an almost endless list of different structures. These features open perspectives for numerous applications, such as the reaction medium for chemical synthesis, electrolytes for batteries, solvent for gas sorption processes, and also membranes for gas separation. In the search for better-performing membrane materials and membranes for gas and vapor separation, ionic liquids have been investigated extensively in the last decade and a half. This review gives a complete overview of the main developments in the field of ionic liquid membranes since their first introduction. It covers all different materials, membrane types, their preparation, pure and mixed gas transport properties, and examples of potential gas separation applications. Special systems will also be discussed, including facilitated transport membranes and mixed matrix membranes. The main strengths and weaknesses of the different membrane types will be discussed, subdividing them into supported ionic liquid membranes (SILMs), poly(ionic liquids) or polymerized ionic liquids (PILs), polymer/ionic liquid blends (physically or chemically cross-linked ‘ion-gels’), and PIL/IL blends. Since membrane processes are advancing as an energy-efficient alternative to traditional separation processes, having shown promising results for complex new separation challenges like carbon capture as well, they may be the key to developing a more sustainable future society. In this light, this review presents the state-of-the-art of ionic liquid membranes, to analyze their potential in the gas separation processes of the future.

This study evaluates the performance of photoelectrocoagulation, peroxi-electrocoagulation, and peroxi-photoelectrocoagulation for the removal of the antiviral drug lamivudine formulation from wastewater by a stainless-steel electrode. To investigate matrix effects for this oxidation process, the influence of substrates such as urea and simulated wastewater (SWW) was studied. Moreover, degradation kinetics and energy efficiency are also discussed. Results indicate that the removal efficiency was in the order of peroxi-photoelectrocoagulation > peroxi-photoelectrocoagulation (in the presence of urea) > peroxi-photoelectrocoagulation (in the presence of SWW) > peroxi-electrocoagulation > photoelectrocoagulation. In peroxi-photoelectrocoagulation, the 96% degradation of lamivudine formulation indicates a nearly complete degradation of lamivudine. In this process, the presence of urea and SWW resulted in a substantial reduction of chemical oxygen demand (COD) decay. Kinetic studies using linear pseudo-first and pseudo-second-order reaction kinetics showed that the pseudo-first-order equation effectively described the removal of lamivudine formulation. The highest energy consumption per kgCOD decay (i.e., kWh kgCOD− 1) was obtained for the photoelectrocoagulation process, while the lowest energy consumption was obtained for peroxi-electrocoagulation, for all electrolysis times. The peroxi-photoelectrocoagulation process was shown to be an effective and energy-efficient technique for removing the antiviral drug lamivudine formulation from wastewater.

The increasing adoption of ultra-low pressure (ULP) membrane systems for drinking water treatment in small rural communities is currently hindered by a limited number of studies on module design. Detailed knowledge on both intrinsic membrane transport properties and fluid hydrodynamics within the module is essential in understanding ULP performance prediction, mass transfer analysis for scaling-up between lab-scale and industrial scale research. In comparison to hollow fiber membranes, flat sheet membranes present certain advantages such as simple manufacture, sheet replacement for cleaning, moderate packing density and low to moderate energy usage. In the present case study, a numerical model using computational fluid dynamics (CFD) of a novel custom flat sheet membrane module has been designed in 3D to predict fluid flow conditions. The permeate flux through the membrane decreased with an increase in spacer curviness from 2.81 L/m2h for no (0%) curviness to 2.73 L/m2h for full (100%) curviness. A parametric analysis on configuration variables was carried out to determine the optimum design variables and no significant influence of spacer inflow or outflow thickness on the fluid flow were observed. The numerical model provides the necessary information on the role of geometrical and operating parameters for fabricating a module prototype where access to technical expertise is limited.

Separation and purification on molecular level from organic solvent mixtures are of paramount importance in industries. Organic solvent nanofiltration (OSN) is a pressure‐driven membrane separation process providing an attractive alternative to conventional energy‐intensive technologies. However, devising a solvent stable, scalable membrane with high permeability and excellent selectivity is still a challenge. Interfacially polymerized thin‐film composite (TFC) OSN membranes integrating an ultrathin selective layer and a porous substrate layer are expected to revolutionize advanced membrane separations. New materials and new strategies to achieve a solvent resistant, highly permeable, and highly selective membrane have been developed in recent years. This review analyses the development of the state‐of‐the‐art interfacially polymerized TFC OSN membranes from the view of structures, materials, and methodologies. First, the emerging structures of current TFC OSN membranes are discussed. The exploitation of new materials (polymers, (nano)fibers, inorganic materials) for the preparation of substrate layer is updated. The advances of new aqueous/organic monomers for synthesis of the selective layer are summarized. Furthermore, the proposed strategies for designing permselective TFC membranes are highlighted. Finally, the challenges together with the future prospects of interfacially polymerized TFC membranes for OSN are proposed.

Desalination via pervaporation has been considered as an attractive membrane process for obtaining clean water from non-potable saline sources, which has advantages, i.e., it is superior in salt rejection and has the capability of coping with high-salinity feed solutions. In the pervaporation process, the membrane material plays the key factor because it is governing the overall efficiency. This overview of nanocomposite pervaporation membranes for desalination mostly emphasizes on membrane materials, the effect of operating parameters on pervaporation performance, and the current research towards the development of nanocomposite membrane. Nearly all types of membranes ever stated in pervaporation desalination are mentioned, based on polymers, inorganic materials and hybrid organic-inorganic materials (nanocomposite) with their performance in terms of water flux and salt rejection.

A series of cellulose triacetate/Ludox‐silica nancomposite pervaporation membranes was successfully prepared via solution casting, aiming to improve the performance of cellulose triacetate membranes for desalination. The fabricated nanocomposite membranes were characterized to study the membrane morphology, chemical composition, mechanical properties, and surface hydrophilicity. Furthermore, the desalination performance was investigated as a function of silica (SiO2) loading (ranging from 1 to 4 wt%) and feed concentration at 30 and 60 g/L of sodium chloride (NaCl). Pervaporation experiments showed that incorporating 4 wt% SiO2 into a cellulose triacetate (CTA) membrane increased the water flux by a factor 2.5 compared with pristine CTA (from 2.2 to 6.1 kg m−2 h−1) for a 30 g/L NaCl feed solution at 70°C, while the salt rejection remained above 99%. The CTA/4 wt% SiO2 membrane was found to have only 21% flux reduction when tested with a 60 g/L NaCl feed solution, without changes in membrane selectivity. This suggests that the developed CTA/Ludox‐SiO2 nanocomposite pervaporation membrane is suitable for desalination.

High-performance positively-charged nanofiltration (NF) membranes have a profound significance for water softening. In this work, a novel monomer, tris(3-aminopropyl)amine (TAEA), with one tertiary amine group and three primary amine groups, was blended with trace amounts of piperazine (PIP) in aqueous solution to fabricate a positively-charged NF membrane with tunable performance. As the molecular structures of TAEA and PIP are totally different, the chemical composition and structure of the polyamine selective layer could be tailored via varying the PIP content. The resulting optimal membrane exhibited an excellent water permeability of 10.2 LMH bar−1 and a high rejection of MgCl2 (92.4%), due to the incorporation of TAEA/PIP. In addition, this TAEA NF membrane has a superior long-term stability. Thus, this work provides a facile way to prepare a positively charged membrane with an efficient water softening ability.

Polyamide membranes dominate the membrane industry; yet in their use they have a fundamental challenge to break through the upper bound due to an uncontrollable, excessive crosslinking degree. A novel trend is the development of microporous polymeric membranes with rigidly intrinsic pores for rapid and precise molecular separation. Advanced microporous organic polymers (MOPs), divided into crystalline (e.g., COFs) and amorphous (e.g., PIMs, PAFs, CMPs, POCs, HCPs, etc.) catalogues, have proven promising in the development of molecular sieving membranes. Different from traditional polymers with dynamic microporosity, MOPs have sturdy and well-defined pore architectures due to a significant reduction of segmental chain motion, enabled by molecular-level design of the void-forming elements. MOPs have swiftly evolved as a promising alternative to conventional materials due to their intriguing inherent attributes, including robust organic backbone, persistent porosity, and high surface area. This review commences with the introduction of the MOP categories and elucidates their critical characteristics and advantages for membrane fabrication. In addition, recent breakthroughs on ultrahigh permeability MOP-based membranes based on molecular-level design approaches are highlighted, aiming at an in-depth understanding of the structure-function correlation of MOP membranes. Furthermore, a summary of applying MOP membranes for rapid molecular separations such as gas separation, water treatment, separation in a solvent phase, pervaporation, and fuel cells is outlined. Finally, a concise conclusion, current limitations as well as future opportunities and directions on the developments and applications of MOP membranes are presented.

Asymmetric polyphenylsulfone (PPSU) membranes were fabricated by a non-solvent induced phase inversion method. Glycerin and silica nanoparticles were added into the polymer solution to investigate their effects on the material properties and gas separation performance of prepared membranes. The morphology and structure of PPSU membranes were analyzed by scanning electron microscopy (SEM), the surface roughness of the selective layer was analyzed by atomic force microscopy (AFM), and the surface free energy was calculated based on the contact angle measurements by using various solvents. The gas separation performance of PPSU membranes was estimated by measuring the permeability of CO2 and CH4. The addition of glycerin as a nonsolvent into the polymer solution changed the cross-section structure from finger-like structure into sponge-like structure due to the delayed liquid-liquid demixing process, which was confirmed by SEM analysis. The incorporation of silica nanoparticles into PPSU membranes slightly increased the hydrophilicity, which was confirmed by water contact angle results. PPSU membrane fabricated from the polymer solution containing 10 wt.% glycerin showed the best CO2/CH4 selectivity of 3.86 and the CO2 permeability of 1044.01 Barrer. Mixed matrix PPSU membrane containing 0.1 wt.% silica nanoparticles showed the CO2/CH4 selectivity of 3.16 and the CO2 permeability of 1202.77 Barrer.

The increasing demand of raw materials and the risk of fossil resources depletion is a motivation for the development of new bio‐based routes for the synthesis of chemicals. The use of non‐renewable natural resources, such as fossil fuels, and the generation of greenhouse gases lead to severe environmental problems. However, one of the challenges of using renewable biomass resources to produce building block molecules is to achieve an efficient and economically viable purification step. The complexity of the mixture involves generally high separation costs. Separation processes such as distillation and liquid–liquid extraction have been proposed to purify target biobased compounds. However, the high energetic cost associated with such processes is pushing the current research towards the development of alternative solutions. In this context, membrane technology, such as pervaporation, is an interesting solution to minimize the energy consumption of the process. This review highlights the main parameters and factors that impact the performance of pervaporation in the separation of complex bio‐based chemical mixtures. Coupling effects, which are among the critical issues in pervaporation, are discussed in detail. Hybrid processes in which both reaction and distillation are performed during the pervaporation process are also addressed. This article is protected by copyright. All rights reserved.

Anticancer drugs have been detected in the aquatic environment, they have a potent mechanism of action and their consumption is expected to drastically increase in the future. Consequently, it is crucial to routinely monitor the occurrence of anticancer drugs and to develop effective treatment options to avoid their release into the environment. Prior to implementing a monitoring program, it is important to define which anticancer drugs are more prone to be found in the surface waters. In this study the consumption of anticancer drugs in the Lisbon region (Portugal), Belgium and Haryana state (India) were used to estimate the concentrations that can be expected in surface waters. Moreover, one important aspect is to define the major entry route of anticancer drugs in the aquatic environment: is it hospital or household effluents? The results disclosed in this study showed that in Belgium and Lisbon, 94 % of the total amount of anticancer drugs were delivered to outpatients, indicating that household effluents are the primary input source of these drugs and thus, upgrading the treatment in the domestic wastewater facilities should be the focus.

Polymer-based CO2 selective membranes offer an energy efficient method to separate CO2 from flue gas. ‘Top-down’ polyelectrolytes represent a particularly interesting class of polymer materials based on their vast synthetic flexibility, tuneable interaction with gas molecules, ease of processability into thin films, and commercial availability of precursors. Recent developments in their synthesis and processing are reviewed herein. The four main groups of post-synthetically modified polyelectrolytes discern ionised neutral polymers, cation and anion functionalised polymers, and methacrylate-derived polyelectrolytes. These polyelectrolytes differentiate according to the origin and chemical structure of the precursor polymer. Polyelectrolytes are mostly processed into thin-film composite (TFC) membranes using physical and chemical layer deposition techniques such as solvent-casting, Langmuir-Blodgett, Layer-by-Layer, and chemical grafting. While solvent-casting allows manufacturing commercially competitive TFC membranes, other methods should still mature to become cost-efficient for large-scale application. Many post-synthetically modified polyelectrolytes exhibit outstanding selectivity for CO2 and some overcome the Robeson plot for CO2/N2 separation. However, their CO2 permeance remain low with only grafted and solvent-casted films being able to approach the industrially relevant performance parameters. The development of polyelectrolyte-based membranes for CO2 separation should direct further efforts at promoting the CO2 transport rates while maintaining high selectivities with additional emphasis on environmentally sourced precursor polymers.

Two supported ionic liquid membranes (SILM) based on 1-octyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([C8MIM][NTf2]) and N-octyl-N-methylpyrrolidinium bis(triuoromethanesulfonyl)imide ([C8C1Pyrr][NTf2]) were prepared and studied for the pervaporation separation of binary mixtures of dimethyl carbonate (DMC)/methanol. Scanning electron microscope (SEM) analyses were carried out to evaluate the cross section morphology of the porous membranes before and after incorporating the ionic liquids. The pervaporation performance of SILMs was found to be highly concentration dependent. At low methanol concentration (0.2 M fraction), both SILMs tend to preferentially permeate DMC. In general, the SILM based on [C8MIM][NTf2] exhibited a better performance than the one with [C8C1Pyrr][NTf2]. Under optimal conditions, the SILM composed of [C8MIM][NTf2] enabled a transmembrane flux of 0.739 kg/m2h, a DMC/methanol selectivity of 67 and separation factor of 21 at 30 °C at 0.8 M fraction of DMC. However, at high concentration of methanol, the permeance of methanol increased due to coupling effects therefore decreasing the membrane selectivity to around 2.

Membrane distillation (MD) is a promising desalination process especially in small scale systems. However, the lack of commercial MD membranes severely impedes the industrialization. Although various approaches have been explored to develop high-performance membranes, the complicated processing procedures and high cost are two major obstacles to scale up the available membranes. In this study, a facile bottom-up method using water as coagulation bath was proposed to fabricate porous poly(vinylidene fluoride) (PVDF) membranes for direct contact membrane distillation (DCMD) in view of application in desalination. By covering a piece of non-woven substrate on the nascent film followed by immersion into a water bath, a skinless PVDF membrane with an isotropic structure was obtained. The SEM characterization confirmed the formation of a rough top surface and sponge-like granular membranes composed of spherulites. The water contact angles substantially increased from 71.7° for PVDF-N membrane to ca. 144° for bottom-up membranes. The DCMD flux of the bottom-up PVDF membrane was as high as 41.4 kg/(m2 h) with a polymer concentration of 15 wt%, when the feed and permeate temperatures were 70 °C and 20 °C, respectively. This facile, environmentally friendly approach provides the possibility of manufacturing large-scale high-performance MD membranes.
