Abstract

Studies on the sorption of rare-earth metals, uranium, and thorium from nitric acid solutions on different phosphor-containing solid extragents produced by the Russian ZAO Axion-RDM are performed. It is demonstrated that effective extraction of REM on phosphor-containing solid extragents is possible from solutions with HNO₃ concentration up to 0.1 M and extraction of uranium and thorium from solutions of up to 6 M.

稀土金属、铀和钍在俄罗斯制造业含磷固体挤出物上的吸附作用

对俄罗斯ZAO Axion-RDM公司生产的不同含磷固体外加剂从硝酸溶液中吸附稀土金属、铀和钍的情况进行了研究。结果表明，含磷固体外加剂可从浓度高达 0.1 M 的 HNO3 溶液中有效萃取稀土金属，并可从浓度高达 6 M 的溶液中萃取铀和钍。
