摘　　要：解决水污染问题时,绿色水处理剂高铁酸盐受到广泛关注。为全面、系统地归纳高铁酸盐在水处理领域的应用现状及最新研究进展,采用知识图谱分析工具VOSviewer对中国知网(CNKI)数据库和Web of Science(WOS)数据库的1377篇文献进行了可视化分析。结果显示,国内外关于高铁酸盐的研究热点相似,现阶段的研究主要集中在有机物去除、消毒副产物及高铁酸盐的协同技术方面,高铁酸盐单独作为氧化剂、混凝剂和消毒剂对部分有机/无机污染物的去除效果不佳。近年来,基于高铁酸盐联用技术的研究受到重视。总结了国内外研究中高铁酸盐与光催化、铝盐、臭氧、次氯酸盐和(亚)硫酸盐联用等技术在处理污染水质中的应用情况。研究结果表明,联用技术对污染物的处理效果均显著增强,其原理为通过提升高铁酸盐的絮凝沉降能力、促进中间价态铁〔Fe(Ⅴ)和Fe(Ⅳ)〕的生成、产生强氧化性自由基(·OH、SO_(4)^(·-))和延长氧化时间,增强对各类污染物的氧化及去除效果,为高铁酸盐联用技术在水处理领域的应用与发展提供思路和理论借鉴。Ferrate,a green water treatment agent,has received much attention in solving water pollution problems.The knowledge map analysis tool VOSviewer was used to visually analyze 1377 documents in CNKI database and Web of Science(WOS)database in order to comprehensively and systematically summarize the current status and latest research progress of ferrate application in water treatment field.The results showed that the research hotspots on ferrate were similar at home and abroad.The current stage of research mainly focused on organic matter removal,disinfection by-products and synergistic technology of ferrate.The effect of ferrate alone as oxidant,coagulant and disinfectant on the removal of some organic pollutants or inorganic pollutants was poor.In recent years,the research based on ferrate combined technology has received attention.The application of ferrate in combination with photocatalysis,aluminum salts,ozone,hypochlorite and sulfite/sulfate technologies in the treatment of polluted water at home and abroad was summarized.The results showed that the combined technologies had significantly enhanced the treatment effect of pollutants.The basic enhancing principle included increasing the flocculation and sedimentation ability of ferrate,promoting the formation of intermediate valence iron(Fe(Ⅴ)and Fe(Ⅳ)),generating strong oxidizing radicals(·OH,SO_(4)^(·-))and prolonging the oxidation time to enhance the oxidation and removal effect of various pollutants.It provided ideas and theoretical references for the application and development of ferrate combined technology in the field of water treatment.
