中文摘要：

为探索海藻酸钠包埋法制备的固定化活性炭微球对铀（Ⅵ）的吸附效果,进行了固定化活性炭微球吸附铀（Ⅵ）试验。结果显示：在溶液初始p H=5.0、铀（Ⅵ）初始浓度为0.4 mg/L、固定化活性炭微球投加量为0.7 g/L时,反应6 h可以达到吸附平衡,此时铀（Ⅵ）吸附量为1.7 mg/g、吸附率为84.50%。对铀吸附机理的探讨表明,固定化活性炭微球对铀的吸附行为符合Langmuir等温线模型和准二级动力学模型。

英文摘要：

To find the effects of immobilizing activated carbon made by activated carbon and Na-alginate as embedding agents biosorption performances on U（ VI ）, biosorption experiment was conducted on immobilizing activated carbon biosorption on U （VI）. Results showed that at the solution initial pH = 5.0, initial concentration of uranium is 0.4 mg/L, the adsorbent dosage is 0.7 g/L, adsorption equilibrium will obtained for 6 h, uranium adsorption quantity is 1.7 mg/g, uranium adsorption rate is 84.50%. Research of adsorption mechanism revealed that the adsorption of U（VI） by immobilized activated carbon fixes the Langmuir model and pseudo-second dynamics model.
