In this study. a novel copolymer hydrogel according to poly (acrylonitrile-co-sodium styrene sulfonate) (ASD) as an effective adsorbent was prepared 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. https://www.roneverhart.com/1915-Old-Taylor-Bourbon-Bottled-1933-Prohibition-Bottling-Quart-low-fill/
