[交流] 求高手帮忙修改修改文章啊

因为英语不过关，已经被退回来了，是关于COD废水处理方面的，小虫金币不多，就全发了。谢谢了！

刚才弄错了,不好意思
Adsorbent/ferrite composites can adsorb and degrade organics in the COD-rich wastewater treatment. In this study, a rice hull/MnFe2O4 composite (RHM) was prepared via calcination under nitrogen atmosphere and used to treat COD-rich wastewater with the assistance of microwave radiation. Rice hull was deposited on a porous substrate consisted of silica and active carbon, and heat-treated under high temperature. Monodisperse spinel MnFe2O4 nanoparticles whose mean diameter was around 59 nm are distributed on the substrate. With the assistance by microwave radiation, RHM was motivated to a hotspot of adsorption and catalysis which could remove more than 70% COD of wastewater within 6 min. The maximum COD removal was 73.46% when the concentration of RHM was 15 mg/mL-1 and the irradiation time of microwave radiation was6 minutes. 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 was 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. With THE advantages of low cost and rapid processing, this novel rice hull/MnFe2O4 composite could gain promising application in wastewater treating-agent.
