摘要
具有多孔结构的沸石对水中的含氧酸根阴离子不具备吸附能力或吸附能力较差。文中基于阳离子表面活性剂对沸石的改性机理和吸附机理,总结了其在去除水体中重金属的研究现状,指明了阳离子表面活性剂改性沸石的研究方向。利用阳离子表面活性剂对沸石表面进行改性,在提高沸石对含氧酸根阴离子吸附能力的同时,保证对金属阳离子的吸附能力,从而到达更好的重金属去除效果。
Zeolite with a porous structure has no or poor adsorption capacity for oxyacid anions in water.In this paper,based on the modification and adsorption mechanism of cationic surfactant on zeolite,research status of heavy metal removal in water is summarized,and research direction of zeolite modified by cationic surfactant is pointed out.The surface of zeolite modified with cationic surfactant can improve adsorption capacity of zeolite for oxyacid anions and guarantee the adsorption capacity of metal cation,so as to achieve better heavy metal removal effect.
