COMBINED ADSORPTION PREPARATIONS FROM ACTIVE CARBONS, CLAY MINERALS AND NATURAL PLANT PRODUCTS

摘要

Data on activity of the combined adsorbents Ultrasorb, Pectopal and Carboxykam for adsorption of the cations Fe~(2+), Co~(2+), Cd~(2+), Pb~(2+), Zn~(2+), Cu~(2+), Ni~(2+) and radioactive isotope ~(137)Cs from a modeling Ringer salt solution are reported. These adsorbents show high adsorption selectivity for ~(137)Cs from biological media (distribution factors achieve 30,000), and also high binding ability for the cations Sr~(2+), Pb~(2+), Cd~(2+), etc. The opportunity of combining properties of sorbents of various natures in combined structures, offered for use as medicinal substances in oral adsorption preparations (enterosorbents) for directed action in treatment of the ecologically dependent diseases connected with the accumulation of heavy metals (HM) and radionuclides (RN) in the organism, is investigated. The efficiency of the preparation Ultrasorb for removing RN from the human organism by enterosorption is investigated. It is shown that this preparation increases the natural elimination of incorporated RN by 20%. It is established that a 2 week enterosorption treatment lowers 2-3 times the RN blood content of a patient.
