| Abstract: | Arsenic is a kind of substance with high toxicity.Arsenic pollution exists in the groundwater,which would be harmful for human health.The research progresses on the arsenic removal techniques for groundwater were emphatically introduced.The advantages and disadvantages of different techniques were briefly analyzed.New adsorption materials have higher adsorption capacity of arsenic.Combining oxidation method with absorption method and so on is the effective ways to deal with arsenite in the groundwater.Due to low cost and having not the secondary pollution,the biological arsenic-removal method has broad development prospect.Finally,the development direction of the arsenic-removal technique was predicted. |
