Kinetics of continuous exchange of Zn^2^+ ions from solutions with Na^+ ions from thin layer of zeolite A

A model of the kinetics of a continuous exchange of cations from solutions with cations from thin layers of zeolite(s) is developed. Kinetic equations derived on the basis of the model make possible calculations and predictions of the exchange efficiency under different exchange conditions. The validity of the model is confirmed by the correlation between measured and calculated values of the amounts of Zn^2^+ ions in both the layers of zeolite A and the zinc nitrate solutions passed through the layers of zeolite A under different initial concentrations of Zn^2^+ ions in the solutions, different masses of zeolite A in the layers and different flow rates of the solutions through the layers of zeolite A.
