FIELD: process engineering.
SUBSTANCE: invention relates to sorbents based on natural clay material. Sorbent contains increased amount of montmorillonite making at least 71-82 wt %. Sorbent features specific surface of 73.57 - 118 m2/g, total volume of pores makes 0.2 -0.28 cm3/g, and particle size does not exceed 10 mcm. Sorbent represents the product of concentration of clay material on Belgorod region deposit. Said sorbent can be used as enterosorbent for absorption of toxins and for selective extraction of heavy metal ions from fluids.
EFFECT: multi-purpose sorbent.
