Development of a novel pyrite/biochar composite (BMFeS 2 ...As a natural reduction mineral, pyrite (FeS 2), was combined with biochar by simply ball milling technology to synthesize FeS 2 biochar composite (BMFeS 2 BC) and applied for the removal of hexavalent chromium (Cr(VI)) in aqueous solution. SEM, XRD, FTIR, and XPS characterization results showed that the FeS 2 and biochar were successfully combined and biochar suppressed the .
