Journal: Architecture Engineering and Science DOI: 10.32629/aes.v5i2.2279
Abstract
Biochar has been widely used in remediation of water and soil polluted by heavy metals, but its poor catalytic performance, low aromatics and few adsorption sites limit its application. The iron based biochar composite prepared by the iron based compound and biochar can improve the defects of the iron based material easy oxidation and agglomeration while optimizing the performance of biochar, and show good passivation effect of heavy metals. The possible problems in the practical application of iron based biochar composites are analyzed through the research in this paper. The aim is to provide a theoretical basis for the application of iron based biochar composites in remediation of heavy metal pollution.
