一、前言在核裂变过程中,钼和锆是高产额的裂变产物元素,所以在乏燃料中钼和锆的含量较高。核燃料水法后处理工艺的常用介质是硝酸,因此测定硝酸溶液中钼和锆的溶解度是有意义的。对于裂变产物的过程化学的研究工作,溶解度数据也是必要的。关于硝酸溶液中钼和锆的溶解度,前人研究得很少,数据也不全。为此,我们测定了不同浓度的硝酸中不同温度下钼和锆溶解度;还观测了硝酸根和铀浓度对钼和锆的溶解度的影响;获取的数据较全面。
I. Preface In the process of nuclear fission, molybdenum and zirconium are high yield fission product elements, so the content of molybdenum and zirconium in spent fuel is high. The common medium for nuclear fuel aftertreatment is nitric acid, so it makes sense to measure the solubility of molybdenum and zirconium in nitric acid solutions. Solubility data is also necessary for the research work on the process chemistry of fission products. On the solubility of molybdenum and zirconium in nitric acid solution, few previous studies, the data is not complete. To this end, we measured the solubility of molybdenum and zirconium at different temperatures in different concentrations of nitric acid. We also observed the effect of nitrate and uranium concentrations on the solubility of molybdenum and zirconium. The data obtained were comprehensive.
