Abstract

Electrokinetic remediation (EKR) is a proficient, environmentally friendly separation technology for in-situ removal of contaminants in soil/sediment, distinguished for its ease of implementation and minimal prerequisites compared to other remediation technologies. To comprehensively understand the research focus and progress related to EKR of contaminated soil/sediment, a bibliometric analysis was conducted on 1593 publications retrieved from the Web of Science Core Collection (WOSCC) database. This analysis utilized data mining and knowledge discovery techniques through Bibliometrix, VOSviewer, and CiteSpace software. The results revealed a rising trend in annual publication numbers, with China leading in the number of publications. The primary journals in this field included the Journal of Hazardous Materials, Chemosphere, and Separation and Purification Technology. The primary disciplines contributed to this field included "Environmental Sciences", "Engineering, Environmental", "Engineering, Chemical", and "Electrochemistry". Keyword co-occurrence and burst analysis indicated that current EKR-related research mainly focuses on the remediation of soil/sediments contaminated by heavy metals (HMs) and organic pollutants (OPs). Furthermore, the EKR remediation improvement method emerged as the prevailing and future research hotspots and development directions. Future research could integrate numerical simulations and various methodologies to predict and assess the migration of pollutants and the efficiency of remediation efforts. Additionally, these studies could explore the effects of EKR on the physicochemical properties and microbial diversity of soil/sediment to provide a theoretical foundation for applying EKR in soil/sediment remediation.

污染土壤和沉积物电动修复的文献计量学分析与系统综述。

电动修复（EKR）是一种熟练的，环保的分离技术，用于原位去除土壤/沉积物中的污染物，与其他修复技术相比，其易于实施和最低的先决条件。为全面了解污染土壤/沉积物EKR的研究热点和进展，对Web of Science Core Collection （WOSCC）数据库中检索到的1593篇文献进行了文献计量分析。该分析利用了Bibliometrix、VOSviewer和CiteSpace软件的数据挖掘和知识发现技术。结果显示，年度出版物数量呈上升趋势，中国在出版物数量上处于领先地位。该领域的主要期刊包括《危险材料杂志》、《化学圈》和《分离与净化技术》。这一领域的主要学科包括“环境科学”、“工程与环境”、“工程与化学”和“电化学”。关键词共现与突发分析表明，目前与ekr相关的研究主要集中在重金属和有机污染物污染土壤/沉积物的修复上。此外，EKR修复改进方法已成为当前和未来的研究热点和发展方向。未来的研究可以结合数值模拟和各种方法来预测和评估污染物的迁移和修复工作的效率。此外，这些研究可以探索EKR对土壤/沉积物理化性质和微生物多样性的影响，为EKR在土壤/沉积物修复中的应用提供理论基础。

期刊介绍： Environmental Geochemistry and Health publishes original research papers and review papers across the broad field of environmental geochemistry. Environmental geochemistry and health establishes and explains links between the natural or disturbed chemical composition of the earth’s surface and the health of plants, animals and people. Beneficial elements regulate or promote enzymatic and hormonal activity whereas other elements may be toxic. Bedrock geochemistry controls the composition of soil and hence that of water and vegetation. Environmental issues, such as pollution, arising from the extraction and use of mineral resources, are discussed. The effects of contaminants introduced into the earth’s geochemical systems are examined. Geochemical surveys of soil, water and plants show how major and trace elements are distributed geographically. Associated epidemiological studies reveal the possibility of causal links between the natural or disturbed geochemical environment and disease. Experimental research illuminates the nature or consequences of natural or disturbed geochemical processes. The journal particularly welcomes novel research linking environmental geochemistry and health issues on such topics as: heavy metals (including mercury), persistent organic pollutants (POPs), and mixed chemicals emitted through human activities, such as uncontrolled recycling of electronic-waste; waste recycling; surface-atmospheric interaction processes (natural and anthropogenic emissions, vertical transport, deposition, and physical-chemical interaction) of gases and aerosols; phytoremediation/restoration of contaminated sites; food contamination and safety; environmental effects of medicines; effects and toxicity of mixed pollutants; speciation of heavy metals/metalloids; effects of mining; disturbed geochemistry from human behavior, natural or man-made hazards; particle and nanoparticle toxicology; risk and the vulnerability of populations, etc.
