THE PREPARATION OF HIGH PURITY YTTRIUM OXIDE FROM LIQUID-LIQUID EXTRACTION CONCENTRATES BY MEANS OF ION EXCHANGE. Report 257. Period covered: Janiary 21, 1959 to February 27, 1959 March 9, 1959 to April 16, 1959

Technical Report ·
OSTI ID:4114039

>High-purity oxide containing less than 0.1% of total impurities was successfully produced by eluting the liquidliquid extraction feed with 0.3% hydroxyethylethylenediaminetriacetic acid (HEDTA) and 0.5% ethylenediaminetetraacetic acid (EDTA). The HEDTA yielded 74.1% yttrium oxide as high purity based on the amount of product recovered. The EDTA yielded 53.3% yttrium oxide as high purity based on the amount of product recovered. (auth)
