Abstract

The dynamics of ammonium sorption on natural sorbent, consisting of montmorillonite and
clinoptilolite (М45C20), and on its acid- and alkaline activated forms was studied. It was shown that the
alkaline activated sorbent is characterized by the highest value of the total dynamic volumetric capacity.
The dependence of the time of protective action on the dependence of the protective action time on bed
height of alkaline activated sorbent and on flow rate was investigated. Constants of the equation Shilov
were defined. The good agreement between the experimental and theoretical data was shown
