FIELD: process engineering.
SUBSTANCE: invention relates to method of producing sorbents based on transition metal complex. Proposed method comprises treatment of siliceous porous carrier containing hydroxyl groups on its surface by copper chloride water solution, evaporation, drying, treatment by mix of phthalic anhydride and carbamide in the medium of nitrobenzene, filtration, drying of obtained chelate complex of metal on carrier in evaporator at lower pressure.
EFFECT: product with higher activity and yield.
