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
