The peculiarities of ternary ion exchange kinetics in sorbent grains

Abstract

The results of analysis and modeling are presented for the kinetics of ternary ion exchange inside the
resin particle. The data obtained with the use of different models are examined and compared with each
other. The possibility of non-monotonic character of the change in time of the total amount of one of the
components is shown. An increase in the concentration wave amplitude is also demonstrated and explained to
be taking place due to the sphericity of the particle shape of the ion exchanger.
