利用信息可视化软件Citespace对活化过硫酸盐高级氧化技术研究的890篇文献进行分析，分别从国家与机构、共被引文献、高频关键词频次等进行可视化知识图谱分析。结果显示，对该领域研究较多的国家主要为中国和美国，Rastogi A和Liang C J在该领域发表的文献影响率最高，其所在的研究课题组值得关注。通过对热点关键词的分析，得出研究热点主要集中在硫酸根自由基的制备、目标污染物的降解过程以及其动力学的讨论，研究前沿主要是改性多相催化材料碳纳米管催化PMS降解水中抗生素类污染物及垃圾渗滤液。

The data with the subjects of advanced oxidation and persulfate included in the Web of Science database from 1996 to 2019 are served as data source.Citespace,an information visualization software,is used to analyze 890 literatures involving in activated persulfate advanced oxidation technology to generate the country and institution,co-cited literature and high-frequency keyword frequency maps,etc.The results show that the most research literatures in this field come from China and the United States.In the Web of Science database,five highly cited and highly centralized documents are obtained.Rastogi A and Liang CJ have published the most influential literatures in the field,and their research groups deserve attention.Through analyzing hotspot key words,the research hotspots mainly focus on the preparation of sulfate radicals,the degradation process of target pollutants and the kinetics.The research frontier concerns using modified heterogeneous catalytic materials carbon nanotubes to catalyze PMS for degradation of antibiotic pollutants and landfill leachate.
