Nanoscale zerovalent iron/magnetic carbon (NZVI/MC) composites were successfully synthesized by simply calcining yellow pine and iron precursors.NZVI/MC pyrolyzed at 800C (NZVI/MC800) had a higher percentage of NZVI and displayed better resistance to aggregation and oxidation of NZVI than samples prepared at other temperatures.The NZVI/MC800 material was applied for the elimination of U(Ⅵ) from aqueous solutions.The results suggested that the NZVI/MC800 displayed excellent adsorption capacity (203.94 mg/g) toward U(Ⅵ).The significant adsorption capacity and fast adsorption kinetics were attributed to the presence of well-dispersed NZVI,which could quickly reduce U(Ⅵ) into U(1),trapping the guest U(Ⅳ) in the porous biocarbon matrix.The removal of U(Ⅵ) on the NZVI/MC samples was strongly affected by solution pH.The NZVI/MC samples also displayed outstanding reusability for U(Ⅵ) removal after multiple cycles.These findings indicate that NZVI/MC has great potential for remediation of wastewater containing U(Ⅵ).
