Abstract
Corrected selectivity coefficients are determined from the zeolite counter-ion composition and thermodynamic ion-exchange constants by studying ion-exchange equilibria in the system natural heulandite-binary aqueous solution for NaCl, KCl, CsCl, NH4Cl, Pb(NO3)2, LiCl·H2O, and Ca(NO3)2·4H2O. The sorbent composition after ion exchange from multicomponent aqueous solutions of differently charged electrolytes can be calculated in advance using data for the equilibria of binary exchange.
