对于放射性废物固化体的长期浸出试验来说.观察锶、铯等放射性核素在浸出容器壁上的吸附行为有两方面的意义,一方面有助于选择容器材料,另一方面提供了在定量分析浸出物质时是否需要对器壁进行解吸处理的参考依据. 多年以来,在放射化学、海洋化学和辐射监测领域中,对放射性核素在器壁上的吸附行为已经进行过理论的和实用的研究.结果表明,影响核素吸附的主要因素是:核素种类和状态,容器材料及其表面预处理,溶液pH值,被吸附元素的浓度,溶液化
For the long-term leaching test of radioactive solid waste, the observation of the adsorption behavior of radionuclides, such as strontium and cesium, on the wall of the leaching container has two meanings: firstly, it helps to select the container material; on the other hand, Analysis of leachables requires a reference for desorption of the walls of the vessel For many years now the adsorption behavior of radionuclides on the walls has been both theoretically and practically useful in the fields of radiochemistry, ocean chemistry and radiation monitoring The results showed that the main factors affecting the radionuclide adsorption were: the type and state of the radionuclides, the pretreatment of the container material and its surface, the pH value of the solution, the concentration of the adsorbed element,
