生物吸附材料对Cr(Ⅵ)的吸附研究进展

Research progress of adsorption of Cr(Ⅵ) by biosorbent materials

简述了Cr(Ⅵ)的来源及危害,并介绍了修复Cr(Ⅵ)污染水体的常用方法,主要介绍了生物吸附法,具体分析了静电吸附作用、氧化还原作用、络合作用、离子交换作用及氢键作用吸附Cr(Ⅵ)的相关机理,介绍了经济有效及预防二次污染解吸处理。最后,生物吸附材料吸附Cr(Ⅵ)作出展望。

The origin and harm of Cr（ Ⅵ） are briefly reviewed,the common methods for repairing Cr（ Ⅵ）contaminated water are introduced and the biosorption method is mainly introduced. The effects of electrostatic adsorption,redox reaction,complexation,exchange and hydrogen bonding role of Cr（ Ⅵ） adsorption mechanism introduced in order to achieve cost-effective and prevent secondary pollution desorption treatment. Finally,the adsorption of Cr（ Ⅵ） on the biosorbent material is prospected.
