AbstractRed mud (RM) is an industrial waste that needs proper disposal without incurring hazards to the environment. In this study, we used RM and corn straw (CS) to fabricate functional biochar composites (FBCs) via pyrolysis. We fully characterized the changes in morphology and composition on the preparation of FBCs at different pyrolytic temperature and the gaseous products during pyrolysis. It was found that a porous structure was generated on CS, endowing FBCs with the ability to remove dyes in water. Moreover, CaO was created through the decom-position of CaCO3 in RM at similar to 700 degrees C, suggesting that FBCs could be used to neutralize the acidic wastewater. Hence, FBCs showed excellent performance in treating acidic dye wastewater, a common industrial wastewater with high contents of acid and dye and for which disposal is laborious. Additionally, FBCs exhibited magnetism because magnetic zero-valent iron was generated by the reduction of ferric oxide in RM with the CS gaseous product (CO) during pyrolysis. This work provided a dual-win strategy for waste recyclability and wastewater treatment, and the proposed method may have potential applications.
