改性聚丙烯酸钠的合成及其对金属离子Pb^(2+)吸附性能的测试

Different-proportionally Modified Polyacrylate Sodium as Adsorbent of Pb^(2+)

对不同配比下改性聚丙烯酸钠作为吸附剂,吸附重金属铅的吸附容量进行了研究,得出Pb2+的吸附等温线。实验表明,在pH=5吸附时间30分钟1#样对铅的最大吸附容量为906 9mg g。

Using different-proportionally modified polyacrylate sodium as adsorbent,we studied the adsorbing capacity of heavy metal lead in this paper. The experiment shows that when the pH=5 and adsorbtion time is 30minutes, we got the adsorption isotherm. The maximum lead adsorbing capacity of the sample 1~# is 906.9mg/g.
