中文摘要：

本文通过静态试验，研究了羟基磷灰石在不同的pH值、投加量、反应时间、铀初始浓度等条件下对水溶液中铀(VI)的去除效果。实验结果表明，羟基磷灰石具有较强的吸附性能，能有效去除水溶液中铀(VI)。当溶液初始pH值为3.0，羟基磷灰石投加量为1.0 g/L，反应时间为60 min，铀(VI)初始浓度为10 mg/L的条件下，羟基磷灰石对水溶液中铀的去除率达到92.81%-95.04%，对应吸附量为9.28-9.50 mg/g。

英文摘要：

The effects of pH value, dosages of reactive material, contact time and initial U(VI) concentration on uranium removal byhydroxyapatite were studied in the static experiments. The results showed that U(VI) can be effectively removed from aqueous solution byhydroxyapatite, and when the pH value of the solution is 3, the dosage of the reactive material is 1.0 g/L, the contact time is 60 min, andthe initial U(VI) concentration is 10 mg/L, the U(VI) removal rate and the adsorption capacity reach 92.81%-95.04% and 9.28-9.50 mg/g,respectively.
