摘要：

4-(2(1)-Thiazolylazo) resacetophenone oxime forms a pink colored soluble complex with uranium(VI) in buffer solutions of pH 6.0. The colored complex has a maximum absorbance at the wavelength 572 nm and the color is stable for about 48 h. The system obeys Beer's law over the concentration range 0.2-6.0-mu-g of uranium cm-3. The molar absorptivity and the Sandell sensitivity of the complex are 6.2 x 10(4) dm3.mol-1.cm-1 and 0.0038-mu-g cm-2, respectively. Effect of various diversions has been studied and the method was successfully applied for the determination of uranium in rock samples.
