FIELD: chemistry.
SUBSTANCE: invention relates to sorbents used as anion exchangers and method of producing said sorbents. The method involves thermal activation of a MSM-41 sample at 110-140°C for 10-14 hours in a nitrogen stream, reaction of the activated product in form of its suspension in methanol with a solution of N-trimethoxysilylpropyl-N,N,N-trimethylammonium (TMT) in a nitrogen atmosphere, filtering the reaction mixture and drying in air for 20-24 hours.
EFFECT: obtaining organo-inorganic composite materials used as anion exchangers, having narrow pore size distribution and an ordered structure, characteristic for MSM-41 type mesoporous materials.
