Chloride/sulphate exchange on anion resins. kinetic investigation,viii. influence of some physico-chemical properties of the resins

Experimental exchange rates for Cl^-/SO⁼₄ exchange on strictly comparable anion resins in 0.006N solution confirm the unfavorable correlation between kinetics and selectivity.Furthermore, evaluation of the influence of other physico-chemical properties of the resins (i.e., nature of matrix, type of amine, etc) seems to support the hypothesis that chemical interactions, and not only diffusional effects, in the resin phase play a leading role on rate control.
