采用溶剂热法后高温煅烧的方式制备了铁钴双金属复合催化剂,用以活化过一硫酸盐(PMS)降解偶氮染料金橙Ⅱ(OGⅡ)。通过X射线衍射仪、扫描电子显微镜、振动样品磁强计和X射线光电子能谱仪等仪器对复合材料进行了表征。考察了钴复合量、不同去除体系、催化剂投加量、PMS投加量、污染物浓度、pH和共存阴离子等因素对OGⅡ降解效果的影响,并探究了铁钴复合催化剂重复利用的效果。实验结果表明,铁钴复合催化剂可以有效活化PMS降解OGⅡ,在n(Co_3O_4)∶n(Fe_2O_3)=0.1、催化剂投加量为1.0 g/L、PMS投加量为0.4 mmol/L、OGⅡ浓度为30 mg/L、溶液pH为6.2的条件下,反应60 min后,OGⅡ的降解率达到了95.81%,其...

The iron-cobalt bimetallic composite catalyst was prepared by solvothermal method followed by high-temperature calcination to activate peroxymonosulfate (PMS) to degrade the azo dye orange Ⅱ (OG Ⅱ). The composites were characterized by X-ray diffractometer, scanning electron microscope, vibrating sample magnetometer and X-ray photoelectron spectrometer. The effects of cobalt compound amount, different removal systems, catalyst dosage, PMS dosage, pollutant concentration, pH and coexisting anions on the degradation effect of OG Ⅱ were investi...
