Abstract
The radiochemical separation of indium by sulfide precipitation, solvent extraction of the bromide with diethyl ether, extraction with thenoyl trifluoroacetone and anion exchange in hydrochloric acid solution has been critically evaluated. Comparison of the efficiency of separation from 15 representative radioactive tracers showed that the sulfide precipitation lacked specificity as a decontamination step. Its primary utility is for the final preparation of counting plates or as a step preliminary to the determination of carrier yield by hydrous oxide precipitation. Ether extraction of the bromide gave decontamination factors as high as lO/sup 4/ for many dissimilar elements when conditions were well standardized. Thenoyltrifluoroacetone extractions gave decontaminations of 100 to 1000 for most elements. The anion exchange technique, when operated far from equtlibrium with a short column, gave decontamination factors of about 10/sup 3/ for many elements with a procedure that requires 1 hour.
