Medical sorbents are used for reducing the negative effects on humans and animals of radionuclides, toxic metals, pesticides and other technological pollutants, particularly at the site of the Chernobyl accident. Sorbents based on fibrous carbon materials have a special place, especially the enterosorbent (Vaulen) and its modified forms prepared using cellulose hydrate materials. These agents differ from granular sorbents in having more homogeneous composition and structure; they have high internal and external surface areas and good kinetic characteristics for sorption. This property of fibrous carbon sorbents, along with their highly developed and regular porosity, results in rapid contact of the entire surface of the sorbent with the medium, which is important, for example, for the first aid of patients in serious states. Thanks to a complex of valuable properties, fibrous carbon hemo- and enterosorbents are of interest as therapeutic and prophylactic agents for reducing the risk of diseases in unfavorable radioecological conditions. Previous studies have demonstrated that fibrous active carbon (FAC) and fibrous carbon ionites (FCI) have better toxin- and metabolic-sorption and better kinetic characteristics than granular active carbons, which are widely used in clinical practice and are characterized by their selectivity for plasma proteins. In the present report, we compare the properties of the enterosorbent {open_quotes}Vaulen{close_quotes} and its modified forms in terms of sorption of Cs, Sr, Pb, and Cd ions from dilute aqueous solutions of the appropriate salts. 10 refs., 1 fig., 3 tabs.
