Abstract

The sorption of ammonium and calcium were experimentally studied by method of break- through
curves. Equilibrium and kinetic characteristics were obtained by the method of inverse problem solution. It
was shown, that on modified PEI sorbent, ammonium sorption is characterized by the decrease of kinetic
coefficient value; calcium sorption is characterized by the decrease of kinetic coefficient and distribution
coefficient values compared to data on natural zeolite
