海泡石应用于重金属污染土壤治理的研究进展

Research progress on remediation of heavy metal contaminated soil by sepiolite

海泡石是一种天然黏土矿物,因其独特的性质,在重金属污染土壤治理中具有很好的潜力。利用中国知网(CNKI)和Web of Science核心合集数据库(WOS),通过对1993-2023年海泡石应用于重金属污染土壤修复的相关文献进行计量分析,使用CiteSpace对海泡石应用于重金属污染土壤修复领域研究的现状及发展趋势进行总结,旨在为高效修复污染土壤提供参考和借鉴。结果表明:1)国内外对海泡石应用于污染土壤修复研究起步较缓,发文量自2010年开始增加,我国已成为在该领域快速发展的重要力量;2)最主要的聚类分别为“吸附”和“钝化”,代表了目前研究的主要方向;3)通过对国内外数据库文献的比较分析,未来需要以海泡石为基础研发新型钝化材料,并加强对钝化生态效应的研究。

Sepiolite is a natural clay mineral that holds great potential in the remediation of heavy metal-contaminated soils due to its unique properties.This study conducts a comprehensive bibliometric analysis of scholarly literature pertaining to the application of sepiolite in the remediation of heavy metal-contaminated soils,spanning from 1993 to 2023,within the CNKI and the Web of Science Core Collection(WOS)databases.Employing CiteSpace for a synthesis of the extant body of research,the objective is to delineate the current state and emergent trends within the domain of sepiolite utilization for soil remediation,thereby offering valuable references and insights for the enhancement of contaminated soil remediation practices.The results show that:1)Research on the application of sepiolite in contaminated soil remediation has started slowly both domestically and internationally,with an increase in publication volume since 2010,and China has become a significant force in the rapid development in this field;2)The most prominent clusters are“adsorption”and“passivation”representing the main directions of current research;3)Through the comparative analysis of the literature from domestic and international databases suggests that future research should focus on the development of novel sepiolite-based passivation materials and intensify investigations into the ecological ramifications of passivation treatments.
