Efficient use of herbicides for plant protection requires the application of auxiliary substances such as surfactants, stabilizers, wetting or anti-foaming agents, and absorption enhancers, which can be more problematic for environment than the herbicides themselves. We hypothesized that the combination of sulfonylurea (iodosulfuron-methyl) anion with inexpensive, commercially available quaternary tetraalkylammonium cations could lead to biologically active ionic liquids (ILs) that could become a convenient and environment-friendly alternative to adjuvants. A simple one-step synthesis allowed for synthesizing iodosulfuron-methyl based ILs with high yields ranging from 88 to 96% as confirmed by UV, FTIR, and NMR. The obtained ILs were found to possess several favorable properties compared to the currently used sodium salt iodosulfuron-methyl, such as adjustable hydrophobicity (octanol-water partition coefficient) and enhanced stability in aqueous solutions, which was supported by molecular calculations showing cation–anion interaction energies. In addition, soil mobility and volatility of ILs were more beneficial compared to the parental herbicide. Herbicidal activity tests toward oil-seed rape and cornflower revealed that ILs comprising at least one alkyl chain in the decyl to octadecyl range had similar or better efficacy compared to the commercial preparation without addition of any adjuvant. Furthermore, results of antimicrobial activity indicated that they were practically harmless or slightly toxic toward model soil microorganisms such as Pseudomonas putida and Bacillus cereus.

Modern agricultural practices are often based on the use of mixtures of specific herbicides to achieve efficient crop protection. The major drawbacks of commercial herbicidal formulations include the necessity to incorporate toxic surfactants and high volatility of active substances. Transformation of herbicides into herbicidal ionic liquids (HILs) seems to be a promising alternative which allows to almost completely reduce volatility due to ionic interactions. In the scope of this research, we transformed (2-methyl-4-chlorophenoxy)acetic acid (MCPA) into a quaternary ester (esterquat) with the use of derivatives of 2-dimethylaminoethanol. The obtained esterquats were later coupled with (±)−2-(4-chloro-2-methylphenoxy)propionic acid (MCPP) in the form of an anion. The combination of MCPA and MCPA is commonly applied in the UK, EU countries and also in the USA to increase the spectrum of targeted weed species. In the framework of this study, novel HILs with an esterquat moiety incorporating a long alkyl chain (C8, C9, C10, C11, C12, C14) were prepared and characterized in terms of basic physicochemical properties (solubility and volatility) as well as biodegradability. Their phytotoxicity was assessed towards cornflower (Centaurea cyanus) as a model weed and maize (Zea mays) as a crop plant. The presence of the esterquat cation contributed to satisfactory solubility in water and other low polar solvents, which eliminates the need to add exogenous adjuvants. Further experiments indicated that the tested HILs stimulated the germination stage of maize and maintained high herbicidal activity towards cornflower. No significant differences in terms of properties were observed in case of HILs which included alkyl substituents with an odd number of carbon atoms. Future studies should be focused on structural modifications in order to improve the biodegradability as well as field studies for evaluation of commercial applications.

Herbicides such as dicamba, MCPA, 2,4-D or MCPP are applied in the form of sodium, potassium, ammonium salts or esters. Although esters are more biologically active, the downside is their high volatility, which is a hazard to neighboring dicotyledonous plants and spraying workers. Moreover, their commercial preparation requires the use of adjutants, which improve the wettability of the sprayed surfaces. Herbicidal ionic liquids (HILs) were introduced to overcome such drawbacks and proved to be more effective in terms of controlling weeds compared to currently applied commercial preparations. In this study, we investigated the concept of herbicidal ionic liquids which contained dicamba in a surface active cation as a ester substituent as well as 4 CPA, 2,4-D, MCPA, MCPP and clopyralid as an anion. The synthetized compounds were characterized in terms of surface and antimicrobial activity as well as herbicidal efficacy against garden cress (Lepidium sativum). Moreover, hydrolysis was performed using acidic, neutral and alkaline treatment to check the conditions at which dicamba is released from the estarquat. It was revealed that the obtained HILs exhibited excellent surface properties manifested as a tendency to effectively interact with biological membranes at lower doses. This was observed as increased toxicity in comparison to reference herbicidal formulations during direct exposure, however assessment of microbial activity in soil revealed that the ecotoxic effect was limited, most likely due to marginal mobility. Consequently, the tested HILs effectively reduced garden cress biomass production and were notably less volatile compared to commercial herbicides. Our findings present a sustainable concept of more effective usage of well-known herbicides with simultaneous reduction of the environmental burden by limiting the amount of chemicals intentionally introduced for agricultural purposes.

Pharmaceutical compounds are considered emerging environmental pollutants that have a potential harmful impact on environment and human health. In this study, the spiky green horse-chestnut shell was used for the biosorption and removal of acetaminophen from aqueous solution. It was analysed how the parameters, like contact time, pH, mass of biosorbent and temperature, influence the effectiveness of acetaminophen removal from aqueous solutions. The equilibrium was quickly achieved after 10 min (∼60%). The amount of acetaminophen adsorption slightly increased with the increase of the mass of biosorbent, and for example for an aqueous solution containing 10 mg/L of acetaminophen adsorption was increased from 62% to 81%. The promising results obtained at pH ranged between 2 and 9, which shows that the adsorption of acetaminophen did not depend on the pH and it may be a consequence of the predominant microporous sorbent and its surface charge. The result is better correlated to a pseudo-second-order kinetic model of type 2 (r2 = 0.9992) than pseudo-first-order. A sorption mechanism of acetaminophen on biosorbent was also proposed. The sorption of acetaminophen over biosorbent is mainly preceded by hydrophilic interactions between hydroxyl and carbonyl groups in pharmaceutical molecules and hydroxyl and carboxyl groups on the surface of biosorbent.

Algae are widely distributed in the aquatic environment. In the analyzed algae from the Black Sea, metals like cadmium, iron, zinc, copper, lead, and thallium were present. From all of the analyzed elements in the algae, iron was present at the highest concentrations. The presented study confirmed that thallium is accumulated in relatively large quantities (1.60–2.12 μg g−1) by all the studied algae. Cadmium and copper were accumulated at the same level (1.98 μg g−1), which was lower in comparison to the average concentrations determined in the analyzed plant material. The average amounts of zinc were at 0.21 μg g−1 for Ulva. High possibility of accumulation of metals by Ulva and Cystoseira allows to use them as a natural indicator of environmental cleanliness.

Surfactants not only are widely used in biotechnological processes but also constitute significant contaminants of the modern world. Among many reports, there is a shortage of works which summarize the issue of surfactant sorption to biomass in a way that would elucidate the biological factors for analysts and analytical factors for microbiologists. The main factor, which is not as obvious as one would expect, is associated with the susceptibility of analytical approaches to errors resulting from incorrect handling of biomass. In case of several publications reviewed in the framework of this study, it was not possible to establish whether the decrease of the analytical signal observed by the authors actually resulted from biodegradation of the surfactant. This review emphasizes the necessity to consider the possibility of surfactant sorption to microbial cells, which may result in significant detection errors as well as conceptual inconsistency. In addition, a reference study regarding representative surfactants (cationic, anionic and non-ionic) as well as yeast, Gram-negative, Gram-positive bacteria, and activated sludge was provided to highlight the possible errors which may arise from disregarding sorption processes when determining degradation of surfactants. This particularly applies to systems which include ionic surfactants and activated sludge as sorption may account for 90% of the observed depletion of the surfactant. Therefore, a systematic approach was proposed in order to improve the credibility of the obtained results. Finally, the need to employ additional procedures was highlighted which may be required in order to verify that the decrease of surfactant concentration results from biodegradation processes.

Very important in adsorption processes is the preparation of material sorbents and from this reason, the impact of washing agent of raw sorbent was analysed. The adsorption capacity was studied in relation to the function of the equilibrium time, the amount of biosorbent and the initial metal(II) ions concentration. In this research for the sake of comparison, the sorptive properties of out-of-date coffee were compared to coffee washed with different agents (mineral acids and water). The scanning electron microscopy and Fourier transform infrared spectroscopy were used to characterise the biosorbents and to identify the functional groups that participated in metal(II) ions bonding. The obtained results clearly indicate that the out-of-date coffee are effective biosorbent for cadmium(II) and nickel(II) ions from aqueous solution. However, for metal(II) ions removal efficiency could influence sorbent preparation and nickel(II) ions were best adsorbed on coffee washed with water, but cadmium(II) ions on raw biosorbent (out-of-date coffee). The best results of sorption were achieved after the contact time of 30 and 60 min, respectively for cadmium(II) and nickel(II) ions.

Pyridine derivatives such as oximes and amidoximes are widely used in pharmaceutical, analytical and coordination chemistry. Increasing interest in this group of compounds as well as their complexing properties and surface activity resulted in their introduction into the environment and change of the ecosystem functioning. Based on this phenomenon, the evaluation of impact O-alkyl-pyridineamidoximes on the soil environment was determined by analysis of changes of metal mobility in soil and plant seed germination. The obtained results indicate that O-propyl-pyridineamidoximes may change the mobility of metals in soil and influence the germination and development of plants. The introduction of these compounds to soil resulted in the reduction of metal (Cu, Pb, Fe) mobility in the soil matrix. This effect resulted in the retention of metals in the soil and inhibition of their mobility. This phenomenon suggests the possibility of using the analyzed compounds in the remediation process as a stabilizing factor. Pyridineamidoximes at a concentration below 100 mg/kg of soil did not influence the seed germination and plant development.

The adsorption of copper(II) ions from aqueous solutions by the green horse-chestnut shell was studied in a batch adsorption system. It was determined how the parameters of the adsorption process, such as time, pH, copper(II) ions concentration and sorbent dose, influence the effectiveness of copper(II) ions’ removal. The adsorption process was fast and equilibrium was established about 10 min, and near 95–97% of Cu(II) ions were removed from aqueous solution. Maximum copper(II) ions’ adsorption occurred at around pH 5. The adsorption kinetics are also described, using pseudo-first-order model and pseudo-second-order model of type 1 and 2. A comparison of the kinetics models on the overall adsorption rate showed that the adsorption system was best described by the pseudo-second-order model of type 1 (r2 = 0.999) for all initial concentrations. Another key part of this study was the use of the Freundlich model to determine the adsorption isotherm and the experimental data were in strong correspondence with this model.

The activated carbon was modified by the wet method with a solution of ammonium persulfate at room temperature with different times. Kinetics studies showed that the modification took place mostly during the first 60 min of the process. The physicochemical properties of the obtained carbon were evaluated by thermogravimetric studies, Raman and FTIR spectroscopy, elementary and BET analyses. Furthermore, the fabricated material was applied in symmetric capacitors operated on the three aqueous electrolytes (1 M H2SO4, 6 M KOH and 1 M Na2SO4). Mild conditions of the modification process are optimal to obtain electroactive groups on the carbon surface, which make this material useful in a supercapacitor application. In our studies, we noticed that this type of functional groups mainly appears on the surface of the activated carbon, in the first oxidation stage. With prolonged oxidation, they may transform into undesirable groups. The results show that this kind of modification improves the capacity of all the tested supercapacitors. It was connected mainly with an increase of the carbon material’s wettability and in the case of capacitor operated in acid and base electrolytes due to a redox reaction of oxygen functional groups.

The effect of different variables on the extraction of copper(II) ions such as the concentration of chloride ions, hydrochloric acid, and ligand has been investigated. The results indicate that the extraction ability of the pyridineketoximes towards copper(II) ions depends significantly on the position of oxime group in the pyridine ring. The oxime of 3-ethyl-1-(2-pyridyl)heptan-1-one was determined as the strongest extractant of the tested oximes and metal stripping was possible by the sodium oxalate with 0.2% addition of sulfuric acid. However, the copper(II) complexes with 3-pyridylketxime reextrcation could be effectively done using water or ammonium hydroxides. The oxime of 3-ethyl-1-(4-pyridyl)heptan-1-one formed a stable emulsion during mixing with chloride solution.

The aim of this work was to examine the influence of the concentration of chloride, nitrate, perchlorate, and zinc(II) ions in the extraction process using synthesized hydrophobic 2-pyridyl ketoximes. Results indicated that oximes could extract zinc(II) ions from chloride solutions and that the extraction depended on ligand and chloride ion concentrations. A maximum extraction was observed at 1.0–1.5 M Cl- and at higher chloride solutions the complex-forming power of 2-pyridyl ketoximes slowly decreased. Zinc(II) ions were effectively stripped from the loaded organic phase with water or ammonia solutions in two stages. The regenerated oximes could yet be used again in the extraction of zinc(II) ions and the reagents could be able to extract solutions with similar results as before. The current study shows that 2-pyridyl ketoximes can be used to extract zinc(II) ions from concentrated chloride solutions and that the separation of copper(II) ions from multielemental solutions is possible.
