吸附材料去除水体中砷的研究进展
Research Progress of Arsenic Removal from Water by Adsorbents
摘要
Abstract
In recent years,arsenic pollution has become an urgent and challenging problem due to its high toxicity and carcinogenicity.In the water environment inorganic arsenic ions mainly occur in two states,As(Ⅲ)and As(Ⅴ).It will become a serious threat to human health when the concentration exceeds the allowable limits.Human is at risk of arsenic contamination due to mining,metal smelting,and the widespread use of various arsenic compounds.Existing technologies include precipitation method,ion exchange method,membrane separation method,biological method,electrocoagulation method and adsorption method.However,most of the above technologies have disadvantages,such as high initial cost,high maintenance cost and secondary pollution.Adsorption method has become one of the most commonly used arsenic removal techniques due to its low cost,simple operation and wide range of material sources.Therefore,this paper reviews the research progress of various adsorbents in the removal of arsenic pollution,in order to provide a reference for the removal of arsenic in water.关键词
