Структурные особенности необратимого композиционного сорбента на основе силикатов и алюмосиликатов кальция

Evolution of the short-range order of the composite granular sorbent based on calcium silicates and aluminum silicates is studied in the series: original state – after soaking in distilled water – after sorption of copper. It is shown that irreversible sorbent composition is a hydrolytically active open physico-chemical system. During the synthesis of the sorbent in the environment of H 2 O and CO 2 reactions of defect formation occur resulting in the formation of carbonate spurrite structurally related to calcium silicate. Carbonate spurrite creates additional active sites for sorption of copper to form a stable hydrated mixed carbonate structures.
