Atomic Energy Aims and scope

Abstract

A method is proposed for intensifying sorption extraction of uranium from silicon-containing solutions and pulps using strongly basic anionites with gel and porous structure. The method decreases the degree of poisoning of the sorbent by silicon compounds, increases the saturation capacity of the sorbent with respect to the uranium reaching desorption, and decreases the concentration of uranium in the waste solutions. A multicyclic process of sorption-desorption of uranium under conditions where polymer forms of uranyl are formed was studied. The technological scheme of the silicon desorption process is presented. 3 figures, 2 tables, 6 references.
