In the reprocessing of irradiated uranium (Purex process) it is necessary to determine uranium extracted in TBP-kerosene, and a polarographic method is proposed for this purpose. Less than 1 g of the sample, TBPkerosene solution, is weighed into a electrolytic cell, and 10.0 ml of the supporting electrolyte (mixture of 100 ml of 2N sulfuric acid, 90 ml of ethyl alcohol and 10 ml of 0.4% Tween-80 ethyl alcohol solution) is added. The solution is mixed and deaerated by passing nitrogen for about 10 minutes, and then it is subjected to polarography (-0.6 approximates -1.2 v vs Hg). The proposed method is simple and suitable for remote handling. Ten to 80 mg of uranium in up to 1 g of TBP- kerosene can be determined without the effects of radiation damage. (auth)
