- Аннотация: The inverse problem of searching ion-exchange isotherms from effluent concentration-time histories obtained by column experiments in displacing one ion by the other based on the mathematical model of nonequilibrium sorption dynamics has been solved. Elution curves for binary Na+-H+ and H+-Na+ exchange on impregnated sulfonate ion-exchangers with different capacities have been obtained for 0.001 M solutions of chlorides. Frontal analysis (direct and reverse) of 0.001 M HCl-NaCl mixtures of different compositions on the same resin samples have been carried out. The results of the first series of experiments have been used for calculating ion-exchange isotherms and for comparison with equilibrium data obtained in the second series. Computed isotherms demonstrate satisfactory fit with equilibrium data obtained for the same couple of ions (Na+ and H+) under the same conditions in independent experiments.
