“…With ILs as side groups, poly(ionic liquid)s (PILs) inherit most of the advantages of ILs, especially the large adsorption capacity. [16][17][18] Therefore, PILs are supposed to be good candidates for the absorption of polysulfides. 19,20 Studies have shown that some strategies using PIL can effectively enhance the adsorption of polysulfide species in the electrolytes to improve the electrochemical performance of Li-S batteries, such as rational regulation of polysulfide behaviors with a polymeric zwitterion, 21 functionalizing the PE separator with PIL 22 or using PIL containing sandwich-type functional nanomats.…”

“…[22] With the increase in food safety and health concerns, new separation or cleanup methods have been required to extract fipronil from contaminated agricultural lands, water and foods. Recently, adsorption process has attracted more attention for the removal studies of pesticides from aqueous solutions, soil, water and food matrixes [23][24][25][26][27][28] due to its simple applicability, reusability, high removal capacity and lower cost. In adsorption based separation processes, different types of adsorbents are used and the selection of the adsorbent depends on the porosity, pore structure, nature of its adsorbing surfaces, surface functional groups and most importantly applications.…”

Fipronil, as a broad use insecticide, is regulated under directives and standards in many countries since it is classed as Class II moderately hazardous pesticide and Group C possible human carcinogen. In this study, amine coated iron oxide (NH 2 À Fe 3 O 4 ) is used as a new adsorbent with high adsorption capacity in the removal of fipronil from aqueous solution and eggshells.The adsorption performance was studied through batch adsorption under different concentrations of fipronil (10-200 μg/mL), different nanoparticles amount (0.1-1 mg) at different pH (4.5-6.0) and temperature (25-75 °C). Results showed that NH 2 À Fe 3 O 4 nanoparticles (0.1 mg) have excellent adsorption efficiency (97.06 %) at 25 °C, and pH 5.5. It also showed higher adsorption capacity towards fipronil sulfide, fipronil sulfone and fipronil desulfinyl with removal efficiencies of 92.82 %, 86.35 % and 76.24 % from aqueous solution and 97.62 %, 76.97 % and 62.65 % from eggshells, respectively. Fipronil adsorption process on NH 2 À Fe 3 O 4 nanoparticles showed best fitting to Langmuir adsorption isotherm indicating monolayer chemical adsorption by physicochemical interactions spontaneously on homogenous surfaces. Having higher adsorption capacity and reusability NH 2 À Fe 3 O 4 nanoparticles were shown to be effective adsorbents for removal of fipronil from aqueous solution and eggshells.

“…Thus, the use of adsorbent-based techniques such as stir bar sorptive extraction [14], solid-phase micro-extraction [14,15], and magnetic solid-phase extraction [16,17] have gained growing attention in recent years. These adsorption techniques are particularly suitable because of their simplicity, 'green' nature, as they are conducted in water, and the availability of a wide range of cheap sorbents [5][6][7][18][19][20][21][22][23][24]. For instance, natural or modified clays [5,7,11,25], activated carbon [11,26], and zeolites [11,26] have been reported as efficient sorbents for pesticide removal from aqueous solutions.…”

Environmental contamination with pesticides occurs at a global scale as a result of prolonged usage and, therefore, their removal by low-cost and environmentally friendly systems is actively demanded. In this context, our study was directed to investigate the feasibility of using some self-assembled hydrogels, comprising chitosan (CS) and carboxymethylcellulose (CMC) or dialdehyde (DA)-CMC, for the removal of four complex fungicide formulations, namely Melody Compact (MC), Dithane (Dt), Curzate Manox (CM), and Cabrio®Top (CT). Porous CS/CMC and CS/DA-CMC hydrogels were prepared as discs by combining the semi-dissolution acidification sol-gel transition method with a freeze-drying approach. The obtained CS/CMC and CS/DA-CMC hydrogels were characterized by gel fraction yield, FTIR, SEM, swelling kinetics, and uniaxial compression tests. The batch-sorption studies indicated that the fungicides’ removal efficiency (RE%) by the CS/CMC hydrogels was increased significantly with increasing sorbent doses reaching 94%, 93%, 66% and 48% for MC, Dt, CM and CT, respectively, at 0.2 g sorbent dose. The RE values were higher for the hydrogels prepared using DA-CMC than for those prepared using non-oxidized CMC when initial fungicide concentrations of 300 mg/L or 400 mg/L were used. Our results indicated that CS/DA-CMC hydrogels could be promising biosorbents for mitigating pesticide contamination of aqueous environments.
