| Abstract: | A new polymeric resin with amino sulfonic acid pendant functions has been prepared for the extraction of acidic and basic
dyes from water. Beaded polymer supports were prepared by suspension polymerization of vinyl benzyl chloride (0.9 mol) and
ethylene glycol dimethacrylate (0.1 mol). The resulting copolymer beads were modified with amino methane sulfonic acid. The
dye adsorption capacity of the resin was found as 0.16 g dye/g resin for ramazol black and 0.15 g dye/g resin for crystal
violet. The pH depending measurements and dye sorption kinetics of the resin were also investigated. |
