电位滴定法简单可靠，干扰元素少，在燃耗高达１０％的裂变产物及中等量的硝酸存在下不干扰测定，可用于测定后处理工艺溶液中铀含量。在过去报道的文献中，大多数取铀量为２～３ｇ，精度为０．０１％。若用于辐照过的核燃料溶解液时，取铀量约０．２ｇ，精度好于０．２％。为 Potentiometric titration is simple and reliable, with fewer interfering elements. It does not interfere with the determination of fission products with up to 10% burnup and moderate amounts of nitric acid, and can be used to determine the uranium content in the post-treatment process solution. In the past reports of the literature, most of the amount of uranium taken 2 ~ 3g, the accuracy of 0.01%. If used for irradiated nuclear fuel solution, take about 0.2g of uranium, accuracy is better than 0.2%. for
