In this work, -SO3H groups in the material obtained from polyvinyl chloride, a new ion-exchange resin for purifying water from
metal ions, were proven and their physicochemical parameters were determined. Kinetics and isotherms of sorption of Ca 2+ and Mg 2+
ions from aqueous solutions in PVC-SC were studied. The results showed that the adsorption of Ca 2+ and Mg2+ ions from aqueous solutions on PVC-SC was consistent with Langmuir's monomolecular theory. This indicated that PVC-SC was chemisorbed by absorbing Ca 2+ and Mg 2+ ions from aqueous solutions
