Annotatsiya

The polyfunctional hemosorbent "Gemosorb" and pure sericin were obtained from substandard cocoons "Bombyx mori", natural silk threads and their fibrous wastes. Fat-wax and inorganic impurities from the feedstock have been removed by washing with various organic solvents. Pure sericin and fibroin were obtained after treatment of the purified initial raw material. A method has been developed for the isolation of pure sericin in an aqueous medium at high temperatures from substandard cocoons and fibrous waste of natural silk, which does not require additional purification, and its amino acid composition has been determined. A method has been developed for preparation of a fibrous polyfunctional hemosorbent from fibroin by its hydrolysis in an aqueous medium using the methods of ultrasonic dispersion and microwave irradiation. The sorption activity of hemosorbent in model media with the use of vitamin B12 was established. The sorption activity of "Gemosorb" was 95% compared to the sorption activity of coal hemosorbent 82%.
