Under specific geological, geomorphological, climatic and hydrological and hydrochemical conditions, arsenic-containing minerals undergo adsorption and desorption reactions. Therefore the arsenic was released into groundwater and caused the formation of high arsenic groundwater. Based on the previous researches, the mechanism of adsorption-desorption during arsenic migration and intention in groundwater was analyzed and summarized. Effects of competitive adsorption, redox, pH and organic matter on arsenic adsorption-desorption were discussed from the aspects of adsorbate and adsorbent. Three mechanisms on arsenic adsorption-desorption, i.e. electrostatic attraction mechanism, ion exchange mechanism and complexation species mechanism, were summarized. This paper can provide useful help for revealing the mechanism of high arsenic groundwater and conducting arsenic pollution control and treatment. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
