This comprehensive review focuses on the recent progress in using biochar as an efficient adsorbent for the removal of malachite green dye. The exceptional characteristics of biochar, such as cost-effectiveness, high porosity, large surface area, and mass production, have made it widely employed in this field. Various biochar fabrication strategies have been reported, and the technologies and applications for removing malachite green with biochars are discussed in detail. The drawbacks, challenges, and perspectives are also highlighted.
This comprehensive review focuses on the recent progress related to biochar applications as an efficient removal agent for malachite green (MG) dye. Recently, biochar has been extensively employed as an effective adsorbent material through its exceptional characteristics, such as cost-effectiveness, high porosity, large surface area, and mass production. Many strategies are reported for biochar fabrication, including hydrothermal liquefaction and hydrothermal carbonization, pyrolysis, and gasification. The reported technologies for biochar synthesis used to remove MG are covered and discussed in detail. In addition, the key recent applications related to using different biochar adsorbents to remove MG are overviewed and discussed. The drawbacks related to this topic as well as the current challenges and perspectives are highlighted.
