摘要: 利用水热法合成羟基磷灰石,以其去除废水中的铀,研究了羟基磷灰石吸附去除铀的影响因素。试验结果表明,羟基磷灰石对铀的去除率高达95%。pH值、温度、吸附剂的用量和反应时间都会影响其吸附量。去除率与作用时间、羟基磷灰石用量呈正相关,酸性至中性介质有利于对铀的吸附,60 min后吸附反应基本达到平衡。

Abstract: Hydroxyapatite is synthesized by hydrothermal method to remove the uranium from wastewater, and the influence factors in this experiment are discussed. The test results show that the removal efficiency of uranium using HAP reaches up to 95%. The major factors that affect removal efficiency include pH value, temperature, the dosage of HAP and the reaction time. The removal efficiency increases with the reaction time and the dosage of HAP increasing. It is advantageous to the adsorption of uranium by acid or neutral medium. It costs about 60 minutes to meet the adsorption equilibrium.
