FIELD: technological processes.
SUBSTANCE: invention relates to production of organo-mineral sorbents based on natural aluminosilicates. Method of hydrophobic sorbent producing from clinoptilolite tuff involves clinoptilolite tuff heat treatment till constant weight, activation at high temperature in 4.0 M hydrochloric acid solution, washing with water, drying to constant weight, treatment with dimethyldichlorosilane or trimethylchlorosilane solution. Said treatment is carried out at solvent boiling point, followed by washing with toluene and drying.
EFFECT: technical result consists in method simplification with maximum degree of modifier grafting.
