Biochar from diverse wastes: A comprehensive bibliometric analysis of heavymetal adsorption in wastewater

Abstract

This article delves into the utilization of biochar derived from diverse waste sources as an effective adsorbent for removing heavy metals from wastewater. A comprehensive quantitative analysis was conducted, scrutinizing key characteristics of biochar sourced from various waste materials for its heavy metal adsorption potential in wastewater treatment. This analysis is based on an extensive dataset spanning from 2013 to 2023, comprising a total of 608 articles retrieved from the Scopus database. Advanced bibliometric analysis and scientific mapping techniques were employed and facilitated by tools like VOSviewer and Tableau to gain insights and visualize trends in this field. The findings from this analysis indicate a consistent upward trajectory in the publication of research documents over recent years. Several countries have emerged as productive hubs, demonstrating substantial influence within their respective regions through wide-ranging collaborations. Notably, China, India, the United States, South Korea, Australia, and Malaysia stand out as the most influential contributors. Furthermore, this study explores the diverse sources of biochar materials and their efficacy in adsorbing heavy metal ions, shedding light on the relationships between these variables. Keyword analysis was conducted to identify the current hotspots within this research domain. In sum, this paper offers a comprehensive bibliometric perspective on the evolution of biochar derived from various waste sources as a formidable adsorbent for heavy metals in wastewater treatment. It serves as a catalyst for further research endeavors, encouraging scholars to explore novel biochar materials or modifications that can enhance adsorption performance while ensuring stability and efficiency.
