METHOD FOR SORPTION DECONTAMINATION OF LOW-ACTIVITY LIQUID WASTES FROM STRONTIUM Russian patent published in 2001 - IPC

Abstract RU 2176829 C1

FIELD: chemical technology for decontaminating solutions from radioactive elements. SUBSTANCE: liquid wastes are decontaminated from strontium-90 on sulfonated cationite KU-2 in Ni²⁺- form. Cationite in Ni²⁺- form is produced in the course of nickel extraction from rinsing water in electroplating process. Proposed method provides for increasing working cycle of column with sulfonated cationite KU-2 in Ni²⁺- form by 1.5 times. EFFECT: facilitated procedure due to use of nickel-containing sorbent. 2 cl, 1 tbl, 1 ex
