Description

A procedure has been developed of determining chromium traces in cerium dioxids. The procedure is based on solvent extraction of chromium (6) by tpibenzylamine after oxidation by cerium (4) in sulfuric acid medium during heating. Spectpophotometric detepmination of Cr has been carried out using reaction with diphenylcarbazide after Cr reextraction. Down to 2x10-5% Cr can be determined in cerium dioxide
