摘要：

The spectrophotometric determination of uranium by Arsenazo III (Ar-III) method in the presence of milligrams of iron is not possible due to the interference caused by iron. To overcome this problem an anion-exchange method for liquid samples (environment, process stream, tailings, wastewater etc.) has been developed for the separation of milligram concentration of iron from dilute solutions of microgram concentration of uranium prior to the spectrophotometric determination. Dowex 1X8 resin was utilized for the separation of iron and uranium in 0.1 M sulfate media. The elution of loaded uranium on the resin column was done with 4% (v/v) nitric acid. Excellent separation was achieved with 97%-101% recovery of uranium. Afterward, the samples were analyzed by Ar-III method; the results were found in good agreement with the already established dibenzoylmethane and fluorimetric methods of uranium analysis.
