用常规的市售活性炭研究了水溶液中铀的吸附。结果发现，用热硝酸处理氧化活性炭的表面，显着增加吸附容量的铀在近中性和微酸性硝酸盐溶液。平衡数据拟合到简化的Freundlich等温线的氧化和接收样品的比较的目的。在小塔实验中研究了水溶液的净化作用。本文讨论了水溶液中铀吸附的离子交换机理。
The adsorption of uranium from aqueous solution has been investigated using conventional commercially available activated carbons. It was found that treatment with hot nitric acid oxidized the surface of activated carbon and significantly increased the adsorption capacity for uranium in near-neutral and slightly acidic nitrate solutions. Equilibrium data were fitted to a simplified Freundlich isotherm for the purpose of comparison of oxidized and as-received samples. The decontamination of aqueous solutions was investigated in small column experiments. An ion-exchange mechanism of uranium sorption from aqueous solution is discussed.
