摘　　要：近年来,砷污染由于其高毒性和致癌性成为了一个紧迫且具有挑战性的问题.无机砷离子在水环境中主要以As(Ⅲ)和As(Ⅴ)的形式存在,当其浓度超过允许标准时,将对人体健康产生严重威胁.由于矿业开采、金属冶炼和各类砷化物的广泛使用,全球多达2.2亿人正在遭受砷污染的威胁.因此,开发绿色、经济和有效的除砷技术对保护人类健康至关重要.现有的除砷技术包括沉淀法、离子交换法、膜分离法、生物法、电凝聚法和吸附法等.然而,上述大多数技术存在初始成本昂贵、维修成本高和二次污染等缺点.吸附法由于成本低、操作简单和材料来源范围广等优点,成为最常用的除砷技术之一.因此,本文综述了各种吸附剂去除砷污染的研究进展,以期为去除水中不同形态砷提供参考.In recent years,arsenic pollution has become an urgent and challenging problem due to its high toxicity and carcinogenicity.In the water environment inorganic arsenic ions mainly occur in two states,As(Ⅲ)and As(Ⅴ).It will become a serious threat to human health when the concentration exceeds the allowable limits.Human is at risk of arsenic contamination due to mining,metal smelting,and the widespread use of various arsenic compounds.Existing technologies include precipitation method,ion exchange method,membrane separation method,biological method,electrocoagulation method and adsorption method.However,most of the above technologies have disadvantages,such as high initial cost,high maintenance cost and secondary pollution.Adsorption method has become one of the most commonly used arsenic removal techniques due to its low cost,simple operation and wide range of material sources.Therefore,this paper reviews the research progress of various adsorbents in the removal of arsenic pollution,in order to provide a reference for the removal of arsenic in water.
