Abstract
Sorption characteristics of synthetic calcium aluminosilicates (CAS) obtained in the multicomponent CaCl2–AlCl3–KOH–SiO2–H2O system are presented. The isotherms of Sr2+ sorption on CAS from aqueous solutions containing no additional salts were measured for Sr2+ concentration from 0.5 to 11.1 mmol/L and solid to liquid phase ratio S: L = 1: 100. The maximum sorption capacity of synthetic CAS was determined, the phase distribution constants of Sr2+ ions at different S: L ratios were found. The recoveries of Sr2+ ions from solutions containing 0.01 mol/L Ca(NO3)2 and from a solution simulating water of the Mayak plant sewage pond No. 11 were determined.
