在放射性同位素分离,制备和应用的过程中,必须注意超微量放射性同位素的某些特殊行为。但是这些特殊行为往往取决于它们在溶液中的状态(包括离子、络合物,分子和胶体状态)。因此,研究放射性同位素在不同条件下所处的状态,是放射化学中一个重要的基本理论问题。研究放射性钇—90在溶液中的状态,对于了解放射性希土元素的性质具有重要的意义。库巴托夫(Kurbatov)等首先用滤纸过滤法测定了Y~(86)在过滤时被滞留在滤纸上的量与溶液的pH,钇的浓度,以及其他电介质的浓度等因素之间的关系;并且还讨论了放射性钇
In the process of radioisotope separation, preparation and application, we must pay attention to some special behaviors of ultra-trace radioisotopes. But these special behaviors often depend on their state in solution (including ionic, complex, molecular and colloidal states). Therefore, studying the status of radioisotope under different conditions is an important basic theoretical issue in radiochemistry. Studying the state of radioactive yttrium-90 in solution is of great significance for understanding the properties of radioactive rare earth elements. Kurbatov et al. First determined the relationship between the amount of Y ~ (86) retained on the filter paper during filtration, the pH of the solution, the concentration of yttrium, and the concentration of other dielectrics by filter paper filtration ; And also discusses radioactive yttrium
