摘要
介绍了目前国内外采用高岭土吸附处理废水中重金属离子的研究状况,总结了吸附效果,分析了pH值、吸附时间、重金属离子初始浓度、温度、改性方法及共存离子等对吸附效果的影响,探讨了高岭土的吸附机理、等温式与吸附热力学,展望了高岭土吸附重金属的发展趋势和应用前景。
The research actuality of using kaolinite for the disposal of heavy metal wastewater at home and abroad was introduced. The adsorption effects of heavy metals from wastewater on kaolinite are generalized. The influences of pH, adsorption time, initial heavy metals concentration, temperature, modified ways and existing metal irons are analyzed. The adsorption mechanisms, isotherms and thermodynamic of kaolinite are discussed. Furthermore, the development tendency and application prospects of kaolinite in disposal of heavy metal wastewater were forecast.
