摘要
吸附法是一种较为高效、经济的水污染防治技术,其中介孔氧化硅由于具有长程有序性、孔道和表面结构易于调控、高的比表面积和孔隙率等特点,成为一种极具潜力的水污染防治吸附材料。本文概述了介孔氧化硅材料在水体中有机污染物和重金属离子吸附去除中的研究进展,并总结了该领域目前存在的问题。
Adsorption has been proved to be an efficient and low-cost water pollution prevention and control technology. Among various adsorbents, mesoporous silica, with exceptional long-range order, highly tunable textural and surface properties, high specific surface area and porosity, was accepted as a potential efficient adsorbent. Research progress of the application of mesoporous silica in the removal of organic pollutants and heavy metal ions in aquatic environment was outlined, and the existing problems in this research field were snmmarized.
