In recent years, the use of magnetic biochar in wastewater treatment has shown significant effects and attracted scholars' attention. However, due to the relatively short research time and the lack of systematic summaries, it is difficult to provide a more in-depth analysis. This study utilizes RStudio and CiteSpace software to comprehensively analyze the research trends and progress of magnetic biochar in wastewater treatment. The analysis of bibliometrics is performed on 551 relevant papers retrieved from the Web of Science, spanning the period between 2011 and 2022. The most influential countries, institutions, journals, disciplinary distribution, and top 10 authors and papers in this field have been identified. The latest dataset has been used for keyword clustering and burst analysis. The results indicated that: (1) Bin Gao is the most influential author in this field, and high-level journals such as Bioresource Technology are more inclined to publish articles in the field of magnetic biochar. (2) Research in this field has predominantly focused on the removal of heavy metals and organic compounds. Keyword burst analysis shows a shift in research direction towards the removal of complex organic pollutants recently. (3) For the future development of magnetic biochar, an environment-friendly approach, economic viability, and joint technology are the directions that need more exploration. Finally, this paper provides a summary of the various adsorption mechanisms of magnetic biochar and several common modification methods, aiming to assist scholars in their research endeavors.
近年来，磁性生物炭在废水处理中的应用效果显著，引起了学者的关注。然而，由于研究时间相对较短，缺乏系统的总结，难以进行更深入的分析。本研究利用 RStudio 和 CiteSpace 软件，对 2011 年至 2022 年期间 Web of Science 上检索到的 551 篇相关论文进行了综合分析，以探讨磁性生物炭在废水处理中的研究趋势和进展。分析了该领域最有影响力的国家、机构、期刊、学科分布以及前 10 位作者和论文。使用最新的数据集进行了关键词聚类和突现分析。结果表明：（1）Bin Gao 是该领域最有影响力的作者，高水平期刊如《Bioresource Technology》更倾向于发表磁性生物炭领域的文章。（2）该领域的研究主要集中在重金属和有机化合物的去除上。关键词突现分析表明，最近的研究方向转向了复杂有机污染物的去除。（3）未来磁性生物炭的发展方向是环境友好型、经济可行性和联合技术，需要更多的探索。最后，本文总结了磁性生物炭的各种吸附机制和几种常见的改性方法，旨在为学者的研究提供帮助。
