FIELD: chemistry.
SUBSTANCE: invention relates to environmental protection and can be used for treatment of natural and artificial ponds, effluents and industrial liquid wastes. Proposed method comprises treating modified silica gel by huminic acids. Silica gel (0.1-0.5 mm-fraction) is modified by poly(hexamethylene guanidine), rinsed and treated by huminic acids, i.e. peat water-soluble fraction, re-rinsed and dried at 70-80°C in air, or at 40-50°C and 700-730 mm Hg in rotary evaporator.
EFFECT: high-porosity mechanically strong material with high specific surface to absorb oil products and organic contaminants.
