Arsenic (As) is a carcinogen that threatens ecosystems and human health. Due to its high adsorption, microporosity, biochar widely available for soil remediation. This review significantly summarizes the current status of waste biomass feedstock-based metal-modified As-contaminated Firstly, this paper briefly describes sources hazards As in soil, secondly, lists eleven feedstocks preparing biochar. Agricultural, domestic, forestry wastes provide plentiful source preparation. Single or multi-metal modifications such as iron (Fe), manganese (Mn), cerium (Ce) can effectively improve Arsenite [As(III)] arsenate [As(V)] adsorption capacity The primary mechanisms removal by include ion exchange, electrostatic attraction, surface complexation, redox transformation, H-bond formation. In conclusion, presents an in-depth discussion on both metal modification, providing constructive suggestions future development remediate soil.
