Abstract: Adsorption and coagulation properties of intercalated montmorillonites were studied in aqueous systems containing cesium and strontium ions. It was shown that cesium sorption results in formation of two monomolecular layers of this component on the surface of the montmorillonite. Adsorption of strontium occurs due to formation of monolayer in pores of the mineral. Besides adsorption, coagulation of the sorbent's particles was intensified. Slow mixing of the solution resulted in particles aggregation, formation of large aggregates and their sedimentation. It was shown that particles aggregation occurred due to decrease of the charge as a result of ions adsorption. Rate constants of the solid phase coagulation were calculated. It was determined for ions with equal electric charges that coagulating ability of the ion increased with the decrease of the radius of hydrated ion. © 2019 Author(s).
