看来确实要求太高了 大家能不能先帮忙改改摘要吧，50 金币 Adsorbent/ferrite composites can adsorb and catalytic degrade organics in the COD-rich wastewater treatment. In this study, we prepared a rice hull/MnFe2O4 composite (RHM) via calcination under nitrogen atmosphere, and used it to treat COD-rich wastewater under assist of microwave radiation. Rice hull was pyrolysed to a porous substrate consisted of silica and active carbon under high temperature treatment. Monodisperse spinel MnFe2O4 nanoparticles with mean diameter of ~59 nm are distributed on the substrate. Assisted by the microwave radiation, RHM is motivated to a hotspot of adsorption and catalysis and can remove more than 70% COD of wastewater within 6 min. The maximum COD removal is 73.46% under conditions of 15 mg•mL-1 RHM and 6 min microwave radiation. Although the BET surface area of RHM is half of rice hull ash (RHA), the COD removal of RHM is 7%~20% higher than that of RHA. It is attributed to the presence of MnFe2O4, which enhanced the catalytic activity of RHM. RHM can be regenerated via water washing. However, the surface area and the maximum COD removal of RHM decrease for each regeneration cycle. This novel rice hull/MnFe2O4 composite is a hopeful wastewater treating-agent with advantages of low cost and rapid processing. |
