METHOD OF EXTRACTION OF STRONTIUM AND CESIUM FROM NITRIC ACID SOLUTIONS Russian patent published in 1994 - IPC

Abstract SU 1432953 A1

FIELD: inorganic chemistry. SUBSTANCE: nitric acid solution containing strontium and cesium is contacted with solution of chlorinated cobalt dicarbamide in the mixture with ortho-nitrochlorobenzene tetrachloride and polyethylene glycol. Then organic phase is washed, and reextraction with nitric acid solution of dimethylsulfoxide, dimethylformamide, trimethylphosphate or phosphonic acid dimethyl ester is carried out. EFFECT: enhanced effectiveness of strontium and cesium isolation by extraction. 2 cl, 2 tbl
