In this work, Azolla filiculoides was used for the bioremediation of a textile effluent and as a potential sorbent for the rejection of Congo red (CR9) dye from a synthetic aqueous solution. The sorbent was characterized, and a pot culture test was carried out to assess the physiological responses in a controlled environment. The response of the plants to the exposure to the emanating pollutants was subordinate. The BOD, COD, and TDS removals were found to be 98.2%, 98.23%, and 90.29%, respectively. Moreover, the dried biomass was studied for the expulsion of CR9, and the process variables were optimized. The maximum CR9 removal was 95% at the optimal conditions of 2 g/L of the sorbent dose at acidic pH. Equilibrium data for adsorption were analyzed using a two-parameter isotherm model. It was observed that the Langmuir isotherm fit with the data (R2 = 0.98) and also had satisfactory lower error values, with its maximum sorption capacity reaching 243 mg/g. The pseudo-second-order kinetics were well fitted (R2 = 0.98). The mass transfer models and the thermodynamic parameters of the system were evaluated. The regeneration studies also showed that the uptake efficacy in the fifth cycle is reduced by 20% when compared with the first cycle. The results show that the biomass was a capable sorbent for the removal of CR9.

Sustainable development is a universally perceived command and it incorporates green or eco-friendly practices. Such spontaneous practices in various sections such as green technology envelop synthesis, processing, handling, and procedure advancement, likewise performance assessment and unwavering quality. Synthesis of green materials is planned as a key empowering influence of sustainable development. The green nanocomposite concept for practical future speaks to a course for making new and innovative materials, in the zone of characteristic polymers. P&C nanocomposites have discovered broad applications in energy storages, aviation applications, biomedical usage, and environmental application. Unique, special, and multifunctional properties emerging because of the scattering of nanoparticles in inorganic matrix are quickly examined followed by its environmental applications. This strategy of P&C nanocomposites and increase in the electrical, mechanical, and catalytic qualities are attributed by the inorganic materials and the polymeric grid, which impact enhanced attributes such as mechanical steadiness, corrosion resistivity, and little coefficients of friction. Cost-proficient synthesis route and great processability with traditional procedures are the two prime prerequisites for bringing more P&C nanocomposites available. This chapter will give a critical overview of the best advances of polymer nanocomposites, mechanical difficulties, challenges in design/implementation, and future perspectives. The chapter will fill in as a thorough asset on applications of P&C nanocomposites.

Chromium (VI) is one of the noxious heavy metals present in the effluents that pose a threat to the living environment. In this exploration, a magnetic nano sorbent was set up by nourishment squander chicken eggshell powder coated with iron oxide in co-precipitation assisted with an ultrasonic bath. The efficacy of CM magnetic nano adsorbent in Cr(VI) removal from its aqueous solution by batch adsorption was investigated. The characterizations indicate that the CM adsorbent was of cubic shape, uniformity in distribution with less agglomeration. The higher crystalline nature and the average particle size of 24 nm were characterized and the magnetization value of 14.46 emu g−1. An endeavor has been made to intend the batch sorption of Cr(VI) by CM magnetic adsorbent embracing Box-Behnken design strategy in response surface methodology (RSM). The most extreme Cr(VI) removal of 92.87 % was acquired at the initial Cr(VI) concentration of 94.5 mg L−1, the contact time of 66.2 min and the solution pH value of 5.5, and mechanical shaking of 200 rpm. The adsorption data for Cr(VI) onto CM adsorbent were well fitted with Langmuir isotherm and pursues the pseudo-second-order kinetics. The materialness of CM adsorbent to expel Cr(VI) from real water such as tested water, surface water, underground water, and tannery gushing water. The proficient recovery CM nano adsorbent was explored through group adsorption-desorption cyclic investigations. The profoundly crystalline CM nanoparticles have been demonstrated to be a promising adsorbent for Cr(VI) redemption from its aqueous mixture.

The extensive discomfort in the expulsion of toxic pollutants even at mild concentrations has demanded the need for prompt methods for the evacuation of dyes and heavy metals. The effective method for depuration of dye from the effluent is by sorption. Chitosan is a bio-polymer which is gaining an increasing interest as one of the sorbents. It was obtained from the crab shells by undergoing several chemical processes and used as an adsorbent for dye, metal removal and also for pharmaceutical purposes. Cross linking it with other co polymers will increase the capacity of adsorption to a maximum level. Fish scales are considered to be a major waste in the food industry and since it takes a long time for decomposing it is considered to be one of the pollutants. Hence it is utilised by converting it into activated carbon by preliminary treatment and into a muffle furnace. The obtained activated carbon is combined with chitosan by using a cross linker and utilised for adsorption mechanism. To analyse the effect of chitosan cross linked with activated carbon obtained from fish scales in adsorption of dye Reactive Blue 9 (RB9) to evaluate the adsorption studies, kinetics, mass transfer studies, thermodynamics of the bio adsorbent.

In this study, the decolourisation of Congo red dye is studied using the natural coagulant Maize Seed Powder (MSP); a suitable alternative for chemical coagulants in electro coagulation (EC) using iron electrodes. The effects of various parameters such as initial dye concentration, pH, applied voltage and time on the decolourisation of dye were studied. The cost of water treatment is increasing due to suspended and colloidal particle load. The coagulation process can be used as a primary step for water and wastewater treatment processes. Among plant materials that have been tested, the seeds of maize have been shown to be one of the most effective primary coagulants in water and wastewater treatment. The removal efficiency of the dye with and without the presence of MSP as a coagulant aid was determined. In the EC process maximum Congo red removal was achieved by using the natural coagulant MSP. Congo red (CR) decolourisation efficiency is 95.23% at a coagulant dosage of 50 mg/lit, pH of 5, operating time of 15 minutes, and a power of 40 volts with iron electrodes. In the absence of coagulant MSP, Congo red decolourisation efficiency was found to be 80.31% at pH of 5, operating time of 15 minutes, and a power of 40 volts with iron electrodes.

The decolourization efficiency of azo dye, Congo red was examined by heterogeneous Fenton reaction using different support like zeolite, activated carbon and fly ash. The iron catalyst was coated into the support by wet impregnation method. Among different support system, zeolite supported iron catalyst (Fe-Z) exhibited maximum decolourization which was used for further studies. The prepared catalyst (Fe-Z) was characterized by scanning electron microscope integrated with energy dispersive x-ray spectroscopy. Experiments were conducted in a batch reactor to examine the effect of operating variables like pH, peroxide concentration [H2O2] and ferrous dosage [Fe2+] in zeolite governing the process. The optimum reaction conditions were found to be [H2O2] = 4 mM, [Fe-Z] =0.4 mM for 0.861 mM of Congo red at pH 3.0 ± 0.2. The process follows a pseudo first order kinetics with a rate constant of 0.012 min−1 (R2 > 0.9). The oxidation products of the heterogeneous system were identified by gas chromatography integrated with mass spectrometry (GC-MS) and the plausible mechanistic pathway was proposed. The results prove that the Fe-Z could be a effective catalyst in decolourizing the Congo red at room conditions.
