New sorbents based on carbonized bentonite - Askan Clay

The paper presents the results of obtaining medical sorbents, studying their physical and chemical characteristics and conducting clinical trials. Carbonized modifications of “Askan clay” (montmorillonite clay from the village of Askana) were obtained by heat treatment of a mixture of “Askan clay” and carbohydrates (glucose, molasses). Carbonization is accompanied by a sharp increase in the overall porosity of “Askan clay”. Samples of carbonized “Askan clay” are characterized by high exchange and sorption capacity. Sorption of cations and anions for carbonized samples occurs in the following sequence: Ba2+ > K+ > Mn2+ > Ca2+ > Mg2+; PO43– > SO42– > Cl–. The possibility of using the carbonized form of "Askan clay" as a sorbent used in medicine has been investigated.
