| 摘 要： | 以开发新型高效除磷吸附剂为目的,以沸石为载体,分别以氧化镧和复合氧化镧、氧化铈为活性组份,对所选的两种吸附剂除磷的性能进行评价。实验表明,以沸石为载体,复合氧化镧和氧化铈为活性组份的吸附剂除磷效果优于以纯氧化镧为活性组份的吸附剂。同时对复合氧化镧和氧化铈为活性组份的吸附剂在不同的实验条件下除磷效果进行研究。结果表明,当吸附剂用量为1g/L,溶液pH为4,接触时间为2.5 h,磷的去除效率可以达到95%以上。

| Abstract: | Removal of phosphorus by rare earth adsorbents lanthanum oxide and ceria oxide,with zeolite as a carrier was studied.Result showed that compound lanthanum oxide and ceria oxide was better than single lanthanum oxide.The removal efficiency of phosphorus reached 95% when the amount of compound lanthanum oxide and ceria oxide was 1 g/l,pH of solution was 4 and reaction for 2.5 hours. |

| Keywords: | removal of phosphorus zeolite lanthanum oxide adsorbent |
