Structural investigations of enterosorbents based on natural silk

Features of an enterosorbent based on the fibroin of natural silk hydrolyzed in acid and alkaline solutions have been investigated by x-radiographic, electron-microscopic, and sorption methods. It has been shown that, regardless of the pH of the solution, a longitudinal-transverse cleavage of the fibroin of natural silk takes placed on hydrolysis, although in the presence of alkali this process is more intensive than in an acid solution of the same normality.Institute of the Chemistry and Physics of Polymers, Academy of Sciences of the Republic of Uzbekistan, Tashkent.
