The PRISMA 2020 method was developed for the review of the literature, using scientific metasearch engines such as Web of Science, Scopus and ScienceDirect. Then, the Boolean formula was determined for analysis. Finally, the relevant articles were synthesized. The results yielded 35 articles of biomass origin, biochar preparation, and remediation efficiency obtained. The result is the following: the most commonly used type of precursor material has been plant (90%); the most commonly used biochar production method was pyrolysis at 500 C° (35%), and the magnetizing agent was FeCb (18%). The maximum lead removal efficiency was 99.50% using the oriental banana as a precursor material in 120 days, in addition to the","pubDate":"2026-10-14","url":"http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S1851-75872026000100008"},"indexado":"2026-10-22T21:54:18.825Z"}}
