PURIFICATION OF YTTRIUM OXIDE--BY ACID EXTRACTION. Report 258. Period covered: May 15, 1958 to June 11, 1958
The investigation of an aqueous acid scrub solution for the purification of the yttrium oxide from the primary contactor was successful while using either 0.4 normal hydrochloric acid or 0.2 normal sulfuric acid. The yttrium oxide was extracted with the aqueous scrub, and the heavy rare earths remained in the organic phase consisting of kerosene, n-decanol, and monododecylphosphoric acid. (auth)
