Abstract: Affected by geological movement and human activities, water pollution by arsenic become a serious threat to human health and life. Treatment of arsenic contamination is one of world focuses. Adsorption is a low cost, easy operating and efficient method to remove arsenic. Currently, absorption properties of various arsenic absorbents have been extensively studied. Biosorbent, which is eco\|friendly and no\|secondary pollution, has attracted widespread attention. This paper reviewed arsenic biosorbents and their adsorption mechanisms, outlining the future research directions and providing reference for the development of new adsorbent materials.

Key words: arsenic, absorbents, sorption, biomass

摘要： 由于地质运动和人类活动的影响，水源的砷污染问题严重威胁到人类的健康生活。砷污染的处理是全球瞩目的研究热点之一。吸附法是一种低成本、易操作、有效的除砷方法。目前各种除砷吸附材料对砷的吸附特性已经被广泛研究。生物吸附剂以其环境友好，无二次污染的特点受到广泛关注。本文就砷的生物吸附与机理进行了综述，阐明了今后的研究方向，为开发新型吸附材料提供参考。
