摘要

放射性废液是核应用产生的副产品。铀在水溶液中能形成多种铀酰配合物。然而，带正电荷的吸附剂对阴离子铀配合物的吸附研究很少。本研究制备了镁氨基粘土（MgAC），并将其用于铀吸附。考察和讨论了pH和硫酸盐浓度对铀吸附的影响。MgAC在pH值3 ~ 5范围内表现出较好的吸附性能。在0.01 M和0.1 M浓度范围内，硫酸盐阴离子对铀的吸附作用明显。

Effect of pH and sulphate ion concentration on the adsorption of uranium onto lamellar magnesium-amino clay

Radioactive liquid waste is a by-product resulting from the nuclear applications. Uranium in aqueous solution is able to form variety of uranyl complexes. However, there are few studies which reported the adsorption of anionic uranium complex by positively charge adsorbent. In the present study, Mg-amino clay (MgAC) is produced and used for the uranium adsorption. The effect of pH and sulphate concentration on the adsorption of uranium is examined and discussed. MgAC showed a superior adsorption capacity at pH ranges 3 ~ 5. The sulphate anion effect to uranium adsorption was apparent at concentration ranges 0.01 M and 0.1 M.
