摘　　要：工业化的快速发展导致含有六价铬(Cr(Ⅵ))的废水排放量日益增加,Cr(Ⅵ)的毒性和高流动性造成极大的环境污染问题。将Cr(Ⅵ)还原成低毒性和低流动性三价铬(Cr(Ⅲ))是当前的有效处理方式之一。与传统方法相比,利用太阳光、电和微波等驱动氧化还原反应进行Cr(Ⅵ)降解,无催化剂消耗,还原剂用量少,且不会造成二次污染和有限资源损耗,成为处理Cr(Ⅵ)污染的有效解决方案。基于此,本文综述了光催化剂、电催化剂及微波催化剂等在还原Cr(Ⅵ)领域的应用现状,在总结分析前人研究成果的基础上,对今后Cr(Ⅵ)催化还原技术的研究方向和重点进行了展望。With the rapid development of industrialization,the discharge of wastewater containing hexavalent chromium(Cr(Ⅵ))is increasing day by day.The toxicity and high mobility of Cr(Ⅵ)cause great environmental pollution.Reducing Cr(Ⅵ)to trivalent chromium(Cr(Ⅲ))with low toxicity and low fluidity is one of the current effective treatment methods.Compared with the traditional methods,the catalytic reduction of Cr(Ⅵ)driven by sunlight,electricity and microwave,has the advantages of no catalyst consumption,less reductant consumption,no secondary pollution and limited resource loss,and has become an effective solution to deal with Cr(Ⅵ)pollution.Based on this,the present paper reviews the application of photocatalyst,electrocatalyst and microwave catalyst for Cr(Ⅵ)reduction.Based on the summary and analysis of previous research results,the research direction and key points of Cr(Ⅵ)catalytic reduction technology in the future are prospected.
