磁性水滑石对水中典型金属离子吸附能力的研究

Study on Adsorption Capacity of Magnetic Hydrotalcite on Typical Metal Ions in Water

研究磁性水滑石对于水体环境污染中典型重金属离子铅、镉、铜、镍(Pb、Cd、Cu、Ni)的吸附过程。参考实际环境的复杂性,本实验通过改变不同重金属与吸附剂的反应时间、反应体系的酸碱度、以及对吸附剂在不同金属上的重复使用性能这几个方面进行研究,并获得比较可靠的实验数据。通过对以上各组实验结果进行分析,以达到对水体污染中典型重金属的科学处理的初步探索,以期为以后的水体重金属污染的修复研究奠定基础。

The adsorption process of typical heavy metal ions lead,cadmium,copper and nickel（Pb,Cd,Cu,Ni） in the environmental pollution of water was studied.With reference to the complexity of the actual environment,this experiment was studied by changing the reaction time of different heavy metals and adsorbents,the pH of the reaction system,the concentration of electrolyte involved in the reaction,and the repeated use of the adsorbents on different metals.And more reliable experimental data were got.Through the analysis of the experimental results of the above groups,the scientific investigation of typical heavy metals in water pollution was achieved,in order to lay the foundation for the future research on the remediation of heavy metal pollution.
