Abstract

The sorption process of calcium (II) and magnesium (II) ions, which cause water hardness with a new sulphocathionite obtained by modifying plasticized polyvinyl chloride (PVC) with sulfur and oxidation with nitric acid, in artificial solutions, under static conditions, were studied. The concentration of the solution during sorption, the duration of sorption, as well as the effect of capillary action was studied. The kinetics of absorption of metal ions in cation exchange resin was analyzed by using pseudo-first and pseudo-second order models. The rate constants in the adsorption process were calculated. According to the correlation coefficient (R2), it was determined that the sorption process proceeds according to the laws of the pseudo-second order reaction. The activation energy of adsorption was calculated by studying the rate of sorption at various temperatures.
