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 (OG ). 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 were investigated, a...
