摘　　要：通过D263NO3-型贫铀树脂对酸法地浸采铀浸出液的吸附试验,分析了NO3-离子转入吸附尾液的过程及规律,初步建立了吸附尾液中NO3-积累平衡点的概念,就积累平衡点的某些特征及其可能得到的应用进行了探索,还将NO3-积累平衡点的概念扩展为树脂上可交换离子在吸附过程中的行为。With the experiment of D263 NO3^- type poor uranium resin adsorbing leaching liquid of in - situ acid leaching of uranium, the procedure and ruh of NO3^- ion entering into adsorption tail liquid are analyzed, and the initial concept of NO3^- accumulation balanced point in adsorption tail liquid is founded. Furthermore, some features of the accumulation balanced point and its potential application are studied, and the concept is extended to the behavior of exchangeability ion in adsorption course on resin.
