  • 摘要: 采用超声辅助化学合成法制备K2FeO4,用X-射线衍射、红外光谱和扫描电镜等对其进行表征。研究了K2FeO4对餐厨垃圾渗滤液中COD和氨氮的处理效果。结果表明,本法制备的K2FeO4具有四方结构,空间群为D2h(Pnma),其产率达到68.2%,纯度高达98.3%。扫描电镜表明,制备的K2FeO4由规则的条状颗粒组成,颗粒之间存在一定团聚。对餐厨渗滤液处理实验表明,在COD初始浓度为140.6 g/L的餐厨垃圾渗滤液中投加0.12 mol/L K2FeO4,调节pH为8.7,经处理24 min后COD去除率达到80.4%,氨氮的去除率达到75.9%。
    Abstract: K2FeO4 was synthesized using a new ultrasonic-assisted chemical method and the microstructure, morphology were investigated by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectrum and scanning electron microscope (SEM).The treatment efficiency of COD and NH4+-N of kitchen waste leachate by K2FeO4 were discussed.Results show that as-prepared K2FeO4 presented a tetrahedral structure with a space group of D2h (Pnma).The yield of K2FeO4 was more than 68.2%with high purity of 98.3%.SEM demonstrated that the K2FeO4 particles were in a regular strip shape with some agglomeration between the particles.When 0.12 mol/L K2FeO4 was added to 100 mL kitchen waste leachate with initial COD concentration of 140.6 g/L and pH was adjusted to 8.7 for 24 min, the removal rates of COD and ammonia nitrogen were 80.4% and 75.9%, respectively.
