对吸附污水中重金属离子新方法的研究

Research of a New Method of the Absorption of Heavy Metal Ions in Waste Water

文章研究了强吸水性树脂对Cu2+、Mn2+、Pb2+等重金属离子的吸附性能,并通过改变强吸水柱树脂(SAR)吸附时间、溶液的浓度、pH值等条件,讨论影响SAR吸附性能的因素.结果表明SAR对Pb2+具有较好的选择性吸附.实验范围内,SAR吸附量随吸附时间、溶液浓度、pH值的增加而增加.

With the absorption of SAR for heavy metal ions as the main research subject, the present paper discusses the factors which affect the selective absorption of SAR by changing such conditions as the absorption duration, the solution concentration and the PH values, etc. Results show that SAR exhibits a better selective absorption for Pb2 ＋ and the absorption ability of SAR is in direct proportion to the absorption duration, the solution concentration and the PH values.
