摘要
水体中的砷严重危害到人体健康,寻求高效廉价的除砷技术已成为研究热点。吸附法因其简单易行、去除效果好、能回收废水中的砷、对环境不产生或很少产生二次污染,且吸附材料来源广泛、价格低廉、可重复使用备受人们关注。综述了当前国内外用不同吸附方法去除水中砷的研究进展,分析了各种方法的吸附性能和特点,提出生物质吸附剂和废弃物吸附剂应成为水体中砷去除的研发热点。
Arsenic and its compounds in wastewater are serious dangers to human health. Therefore,seeking for high-efficiency and inexpensive arsenic removing techniques has become one of the research hotspots. Adsorption received much concern, because it is characterized by simple and convenient operation, good removing efficacy, less secondary pollution to the environment, wide adsorptive materials, low cost, and reusable. The research development of removing arsenic from water by different methods both in China and abroad are summarized. The adsorptive capability and characteristics of various methods are analyzed. It is indicated that biomass adsorbent and waste adsorbent should be the research hotspot of removing arsenic from water body.
