METHOD OF SORPTION RECOVERY OF URANIUM FROM SOLUTIONS AND PULPS Russian patent published in 2004 - IPC

Abstract RU 2226177 C2

FIELD: nuclear power engineering. SUBSTANCE: invention relates to recovering uranium from solutions and pulps containing impurities. Anionites having gel or porous structure are saturated with uranium and saturated sorbent is treated with alkaline agent, to which alkali metal salt, mainly sulfate, was added. After that, anionite is additionally saturated for 2 to 5 h with uranium by bringing anionite into contact with part of commercial desorption product. EFFECT: increased uranium capacity of anionite, increased sorption selectivity, and prevented poisoning of ionite with impurities. 2 cl, 3 tbl, 3 ex
