The high environmental impact of solid and liquid wastes containing toxic elements and metals is having a negative impact on various ecosystems, this work aims to perform a systematic review and bibliometric analysis of scientific production, hoping to understand the retention and absorption capacity of biochar, analysis Capacity of different biochars for certain pollutants including heavy metals; the bibliometric analysis was performed through a review of web of science (WoS) and Scopus databases. The records obtained are analyzed using graph theory and tools such as bibliometrix, Sci2 Tool, Gephi, are divided into three categories: classical, structural and recent, where three perspectives are obtained: uptake of heavy metals, bioavailability and pollutants; Similarly, it was identified that the field of study is new. The main author is Yang Yi, important authors such as Geng Yong and Liang Dong have a fairly high H-index. Additionally, the countries with the highest production in the subject are: CHINA which ranks first, USA with the second place and KOREA with the third place.
