SERICIN AND POLYFUNCTIONAL HEMOSORBENT FROM NATURAL SILK FIBERS

Sarimsakov A.A.1, Yarmatov S.S.1, Khegay L.N.2


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%.
