FIELD: chemistry.SUBSTANCE: invention relates to methods of producing sorbents with a highly ordered MCM-41 type structure. Disclosed is a method of producing mesoporous materials with addition of quercetin and (+)-catechin during synthesis. The method involves preparing a reaction mixture based on Ludox-HS-40, CTABr, NaOH, HO, quercetin or (+)-catechin. The mixture is subjected to hydrothermal treatment, washed with distilled water and a mixture of 96% ethanol with ammonium nitrate, dried and calcined at 550°C.EFFECT: invention enables to obtain MCM-41 type material which is efficient for sorption concentration of vitamins, which relate to a group of flavonoids, and as a carrier in chromatography.9 ex, 3 dwg |
