SOLVENT EXTRACTION PROCESS FOR RECOVERY OF STRONTIUM, RARE EARTHS AND CESIUM FROM RADIOACTIVE WASTE SOLUTIONS

Technical Report ·
OSTI ID:4661648
A new solvent extraction process was developed for the simultaneous extraction of Cs, Sr, and the rare earths from acidic wastes. In this process, designated as CSREX, a mixture of di-2-ethylhexylphosphoric acid (D2EHPA) and 4- sec-butyl-2-( alpha -methylbenzyl) phenol (BAMBP) in a kerosene-type diluent is used as the organic solvent. D2EHPA has a synergistic effect on the extractive properties of BAMBP, broadening the effective extraction pH range for Cs to a range of 3 to 14. Data are presented for the distribution of Cs, Sr, Ce, and Na as a function of D2EHPA and BAMBP concentrations and of phenol extractant. (D.L.C.)
