Abstract

Regularities of the kinetics of sorption of ions India, iron(III) and zinc from model solutions of weak
acid cation exchangers with different functional groups, including aminophosphonate. Installed mix-diffusing
mode sorption process, which is confirmed by the values of the apparent energy of activation. Calculated
coefficients diffusion, the rate constants of external and internal diffusion. To identify the contribution stage
of the chemical interaction of the applied models pseudo-first and pseudo-second order.
