Abstract
The kinetics of ion exchange in polyantimonic acid (PAA) with the composition of Sb2O5 · 3.2H2O are studied. It is shown that sodium and potassium ions replace mobile proton groups and are located in channels of the PAA crystal structure. Diffusion coefficients are calculated in the approximation of the spheric grain model on the basis of the ion exchange data.
