Summary

A spectrophotometric method for direct determination of uranium in carbonate solution has been developed. No extraction or decomposition steps are necessary. The highly sensitive (4-2-pyridylazo) resorcinol, as well as 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol, producing very stable uranium(VI) complexes, were used for its spectrophotometric determination.

The usefulness of the proposed methods was examined by determination of uranium in real samples from a wet-process phosphoric acid estimation of uranium.
