沸石材料的改性及其对水体污染物的吸附性能
Modification of zeolite materials and their adsorption properties for the pollutants in aqueous solution
摘要
Abstract
Adsorption is considered as an effective method in wastewater treatment due to its excellent selectivity,simple operation and less secondary pollution. Natural zeolite materials have attracted much attention of scholars because of their characteristics of rich pore structure, low adsorption costs and high adsorption performance. However,the poor adsorption selectivity, difficult separation with aqueous phase and high regeneration costs have limited their further application. Through modification of zeolite adsorbent,more active sites can be obtained for the adsorption of anionic pollutants. This review presents the latest advances on the modification and preparation of zeolite materials from various precursors. Special emphasis is put on the preparation of zeolite composite adsorbent with different modified materials. This review focuses on the methods and application of modified zeolite materials,as well as the performance in adsorption of water pollutants and the influence factors. Further improving the adsorption selectivity through modification and green regeneration after adsorption will be the core of pushing forward the large-scale application of zeolite materials.关键词
