The magnetic structure, optical properties of copper ferrite in photodegradation and Oxidative desulfurization were investigated in this paper. The product was characterized by XRD, SEM, TEM, EDXS, XPS, VSM, PL and FTIR. The results from XRD obviously revealed the tetragonal spinal structure of CuFe2O4, while the FTIR analysis appeared as a fundamental vibration assigned to oxygen metal at octahedral and tetrahedral sites. The spherical morphology with the size in the nano range was obtained from SEM and TEM analysis, and these results were in agreement with the results from XRD. The magnetic properties were investigated using VSM, and the results showed the highest value of the saturation magnetization (Ms) (80 emu/g) with the low coercive force (72 Oe). The ratio percentage and its purity were explored from EDXM and XPS analysis, and the results obtained showed some carbon on the surface of ferrite, while the analysis of PL luminescent showed many emission peaks back to copper ferrite which was appeared in the visible region. The synthesized material showed very high efficiency to recover, and the degradation of sulfur compound and Azo dyes reached to 93% and 95%; respectively.
