摘要
含Cd^(2+)废水危害人类健康,通过蒙脱石类吸附剂处理Cd^(2+)的研究受到广泛关注。文中对相关报告进行归纳总结,从蒙脱石的理化特性、无机改性、有机改性、复合改性、吸附性能和竞争吸附等方面的阐述表明了蒙脱石及其衍生物去除水体中Cd^(2+)具备的良好可行性。然而,对于吸附的微观机理、多组分重金属废水的吸附和有关蒙脱石改性、再生成本等经济可行性方面还需要进一步深入研究。
The presence of Cd^(2+) in water is harmful to human health.The treatment of Cd^(2+) in water by montmorillonite adsorbents has been attracted extensive attention.In this paper,related reports are summarized,and the good feasibility of removing Cd^(2+) from water by montmorillonite and its derivatives are described from the aspects of physical and chemical properties,inorganic modification,organic modification,compound modification,adsorption performance and competitive adsorption.However,the microscopic mechanism of adsorption,the adsorption of multi-component heavy metal wastewater,and the cost of modification and regeneration of montmorillonite need to be further studied.
