Fluorometric Microdetermination of Uranium. II. Extraction of Uranium [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1950
Abstract A minute amount of uranium suitable for the fluorometric method of determination is effectively precipitated from the solution together with hydrous ferric oxide as co-precipitator. The efficiency of co-precipitation seems to be nearly perfect for the purpose, and the adsorption and the digestion effect were observed in ...
