Abstract:: In order to understand the research and development status of soil heavy metal passivation modified materials and promote its development, the literature on soil heavy metal passivation modified materials at home and abroad from 2011 to 2020 was searched through CNKI and Web of Science databases. The econometric analysis was conducted from the aspects of annual publication, major publication countries, publication types, Top10 most cited papers and Top10 journals in terms of publication volume. The results showed that the annual publication amount of soil heavy metal passivation modified materials increased rapidly from 2017. China has the highest publication amount in this field, but the average citation frequency is low. In China, many modified materials are mainly biochar, nano zero-valent iron and chitosan, and the modification methods are mainly iron base modification, mercapto modification, hydroxyl modification and other modification methods. The papers are mainly published in Environmental Science and Pollution Research, Journal of Hazardous Materials, Chemical Engineering Journal and other foreign journals. It‘s also published in Journal of Agro-Environment Science,Environmental Science, Environmental Pollution & Control and other domestic journals. The main objects of soil heavy metal passivation are cadmium, lead and chromium. Among the top 10 funds in China, national funds account for more than 90%. Based on this, the problems and future development of soil heavy metal passivation modified materials in China are put forward.
