摘要: 含重金属离子废水的排放是环境重金属累积的重要原因之一,而膨润土具有良好的吸附性能并且价格低廉,因此利用膨润土对废水中重金属离子进行吸附成为了当前的研究热点。为了更全面地了解膨润土对废水中重金属离子的吸附过程,对目前国内外相关研究进行归纳总结,从吸附过程的影响因素、等温吸附、吸附动力学、吸附热力学、吸附机理及解吸等方面进行介绍和评述,指出目前研究所存在的问题,指明了今后的研究和发展方向,为推动该技术用于实际废水处理提供理论支持。

Abstract: The discharge of wastewater containing heavy metal is considered to be one of the most important reasons for the accumulation of heavy metal in environment.While,adopting bentonite in heavy metal from wastewater has become a current research hot spot due to its excellent adsorptive characteristics and low cost.In order to have a more comprehensive understanding of the adsorption process of heavy metal with bentonite,the adsorption process of heavy metal with bentonite on the basis of the analysis of related literatures was introduced.The adsorption influencing factors,including adsorption isotherms,adsorption kinetics and adsorption thermodynamic,adsorption mechanism and desorption were introduced and reviewed.Finally,the current problems are concluded and the direction of further research about the adsorption of heavy metal with bentonite is pointed out to promote theoretical support for the practical wastewater treatment with this technology.
