I -'1 .4 *-.v ' a.,* Ari'l polymers of asbestos (A. D. Pedoseev et al . , 1966). Asbestos swells easily In water and slkallne solution. In consequence of which its total surface area Is lncreaso.l. As has been shown earlier, chrys it 12e-.'isbestos possesses a tubular structure, which determines the high specific surface area and a number of colloidal properties, among which we attribute special importance to adsorptive properties. Having compared the capability for adsorption of chrysotile- asbestos, serpentine, calcined chrysotile-asbestos, anthophyllite, tremolite, actinolite and magnesia-arfvedsonite, we established that the greatest capability for adsorption of ionic-molecular substances, and also albumin of the blood serum is possessed by chrysotile-asbestos, brucite and anthophyllite. Thus, after 3 days a charge of chrysotile-asbestos in 100 mg adsorbs 20-30 mg of albumin. The specific surface area of this dust turned out to 2 be the greatest - 20 m /g. Asbestos easily adsorbs carbohydrates, amino acids etc. (Holzapfel, 1952)*' V=" According to contemporary ideas (K. Adamchik, 1952, Benson,.
