Solochrome Black 6 BN in an acetate buffered medium containing methanol reacts with U(IV) to give a blue complex, which permits photometric determination with 5 mu g U/ml to 100 mu g U/ml. In the presence of zinc acetate, uranyl ion also may be spectrophotometrically determined by means of the same dye. From 2 mu g U/ml to 40 mu g U/ml may be determined with a relative error of less than plus or minus 0.05. (auth)
