Effective removal of hazardous cationic dye from polluted water using sulfonated copolymer hydrogel: Synthesis, nonlinear isotherm, and kinetics investigation

In this study, a novel copolymer hydrogel according to poly (acrylonitrile-co-sodium styrene sulfonate) (ASD) as an effective adsorbent was prepared Covers via free radical polymerization of the solution at a ratio of 1:1 to remove cationic crystal violet dye (CV) from wastewater.The prepared hydrogel was thoroughly characterized using FTIR, TGA, S
