Аннотация:A theoretical and experimental study of the diffusion in complex- forming ion exchangers has been made. The theoretical study is based on diffusion- type mass balance equations for the counter ions and co-icon. These equations are solved by using computers. The influence of exchange selectivity and ion mobility on the kinetics of ion exchange in a complexing ionite is discussed. The theoretical deductions have been verified experimentally for exchange in a carboxylic cation exchanger and for exchange in a complex-forming vinylpyridine cation exchanger. The experimetal data agree with the theoretical deductions.
