摘要
水体砷污染严重威胁着人类健康和生态系统,砷污染防治成为全球性环境问题,含砷水处理受到人们的普遍关注.与其它除砷方法相比较,吸附法具有去除效率高,稳定性好,不产生或很少产生二次污染,吸附剂可重复使用等优点,因而备受青睐.本文简要介绍了吸附法除砷的原理与特点,重点综述了矿物质、活性炭、金属(氢)氧化物、生物吸附剂、离子交换树脂和磷酸盐等吸附剂除砷的性能、特点和研究进展.提出介孔材料和生物吸附剂由于其优良的性价比,将成为未来的研发热点.
Arsenic pollution in water exerts great risks on human health and ecosystem,and arsenic pollution prevention has been recognized as a globally environmental challenge.Therefore,the removal of arsenic species from contaminated water has been brought into focus around the world.Compared with other conventional methods,adsorption has attracted considerable attention due to the following advantages such as high efficiency,reliability,not producing harmful byproducts.In this article,the principle and characteristics of adsorption were briefly introduced,and the performance,the features and the corresponding research advance of various kinds of arsenic adsorbents including mineral,active carbon,metal（hydr-）oxide,phosphate,biosorbent and ion-exchange resin were systemically reviewed.The results indicate that mesoporous material adsorbent and biosorbent would be the central issue in the future because of theirs excellent performance relative to the cost.
