CuFe2O4/CuO magnetic nano-composite activates PMS to remove ciprofloxacin: Ecotoxicity and DFT calculation

Bo He et al.

Summary: In this study, CuFe2O4 was attached to CuO using hydrothermal and high-temperature calcination methods. The (111) plane of CuO and (112) plane of CuFe2O4 formed a surface heterojunction, which facilitated the adsorption of PMS. The charge transfer and charge density in the CuFe2O4/CuO/PMS system were investigated using density functional theory (DFT) and transmission electron microscope (TEM). The experimental data showed that both nonradical singlet oxygen (1O2) and active radicals (center dot OH, center dot SO4-) were involved in the degradation of CIP. The degradation pathways and intermediates were proposed using Fukui index and liquid chromatography-mass spectrometry (LC-MS). The study also evaluated the bioaccumulation factor and toxic effects of intermediates using toxicity calculation software. CuFe2O4/CuO demonstrated good reusability and stability. Overall, this study provides valuable insights into the mechanisms of organic pollutants degradation using Fe-Cu catalyst and achieved a CIP removal rate of 86.67% under optimal conditions.
