Experimental kinetics of direct, isotopic and reverse Cl-/SO=4 exchange on different anion resins are presented. At very low concentration (C = 6 × 10-3 N) extremely high resin selectivity toward sulphates occurs (separation factors ranging from 52 to 589). Consequently chemical interaction of interdiffusing species within the resin seems to influence the rate determining step, exception made for isotopic exchange. Application of model equations from Nernst-Planck and SN2 rate theories is discussed

Abstract
Experimental kinetics of direct, isotopic and reverse Cl-/SO=4 exchange on different anion resins are presented. At very low concentration (C = 6 × 10-3 N) extremely high resin selectivity toward sulphates occurs (separation factors ranging from 52 to 589). Consequently chemical interaction of interdiffusing species within the resin seems to influence the rate determining step, exception made for isotopic exchange.
