Advanced oxidation of the pharmaceutical pollutant ciprofloxacin with activatedpersulfate radical on ferrite spinels

Currently, a large number of different drugs are used to treat animal and human diseases. Due towidespread use and improper disposal, they eventually pollute surface and underground waters. Advancedoxidation processes (AOP) can be useful in the treatment of emerging pollutants. Spinels are a group of mixedmetal oxides, which are a suitable option for radical activation in advanced oxidation processes due to theirfavorable structure and morphology. In this research, the removal of ciprofloxacin antibiotic by advancedoxidation process based on persulfate radical activated by spinel ferrite catalysts prepared by co-precipitationmethod was studied and the effect of different precipitating agents in the preparation of spinels on theircatalytic performance was investigated. The results showed that cobalt ferrite spinel performed better thannickel ferrite spinel and manganese ferrite. Besides, the XRD results showed that the catalysts prepared withurea precipitating agent had a more regular crystal structure than other precipitating agents.
