Abstract In this study, phosphoric acid was used as an activator to modify chaff-derived biochar for the obtainment of functional chaff-derived biochar(fCBC), which was rich in active functional groups. Then fCBC was utilized as a carrier material for manganese sulfide (MnS-fCBC), which could be applied to effectively remove cadmium(Cd) in aqueous solution. The effects of initial Cd concentration, initial pH value and dosage of MnS-fCBC on the adsorption capability were systematically evaluated. The MnS-fCBC showed an excellent adsorption performance of Cd. Under the condition of the intial Cd concentration was 200mg/L, solution pH value was 6, adsorbents dosage was 1g/L, the maximum adsorption capacity of MnS-fCBC came to 145.15mg/L. The adsorption reaction was significantly affected by the pH value, and a better removal performance could be obtained under weakly acidic conditions. To characterize the structure of MnS-fCBC, X-ray diffractometer (XRD) and Raman spectroscopy (Raman) was applied, and the removal mechanism of Cd was discussed by batch experiments and characterization results, showing that surface complexation and chemical precipitation were the main mechanisms of Cd removal. Recycle tests showed that the material still had significant Cd removal capability for five successive 24h adsorption-desorption cycles, which showed that MnS-fCBC had high reusability. Therefore, MnS-fCBC could be used as an effective Cd adsorbent for the treatment of Cd-containing wastewater.
