ABSTRACT Due to the vast amounts of toxic metals, oils, and dyes containing wastewater, water pollution is currently a serious health issue for human beings animals. Adsorption these pollutants using biopolymeric‐based hydrogel from wastewater one potent methods due its biodegradability low cost. Herein, porous biodegradable (CS–GL–IL) was synthesized gelatin (GL), chitosan (CS), ionic liquid (IL), acting as an excellent adsorbent pollutants. The maximum percentage swelling obtained CS–GL–IL 480% ± 3% 0.5 g liquid, 0.05 APS, 35 mL at 65°C 1.5 h reaction. process eliminating methyl orange (MO) methylene blue (MB) dye done hydrogel. Numerous methods, including PXRD, SEM, FTIR, rheology, have been used characterization data indicate that Freundlich adsorption isotherm with pseudo‐second‐order kinetics followed dyes. exhibits capacities 1171 mg/g 1062 MO MB, respectively. Furthermore, also exhibited efficiency in detection Ni 2+ Pb 315 370 mg/g, Dye removal remained above 82% even after eight iterations desorption experiments. high potential regeneration capabilities, acts material remediation wastewater.
