| 摘 要： | 采用烧制得到的氧化镁,通过两种途径研究了其对重金属离子废水的处理,结果表明,制得的氧化镁具有很大的表面能和反应活性,当溶液中的Cd2 离子处于低浓度时,加入络合剂后,以Cd2 离子为微粒形成络合物,并在氧化镁的作用下沉淀除去,达到进一步净化水质的目的。同时,处理后的水质远远好于国家规定的排放标准GB 8978-1996。

| Abstract: | Nanocrystalline magnesium oxide was made by baking method.The detail process of heavy metal ions wastewater treatment was investigated by two ways.The result showed that the prepared magnesium oxide has the very strong surface energy and reaction activity.When the solution is in low concentration of Cd2 ion,adding the reagent of coordinate,it could form the coordinate compound.With the effect of magnesium oxide,the Cd2 ion formed the precipitation and removed.This process further gets to the aim to purify water and better than the standard of GB8978-1996. |
