Abstract

Background and Objectives: Among the various types of contaminations, dyes have complicated structure and they are usually toxic and resistant to the biological treatment which enter into environment by industrial waste streams. The aim of this study was the removal of C. I. Acid Red 27dye by photocatalytic processes. Materials and Methods: In the present study, Cu, Mg/TiO2 nanoparticle was synthesized using Sol Gel technique. The physicochemical properties were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM), and energy dispersive X-ray spectroscopy (EDX) techniques. Findings: The XRD data showed anatase and rutile crystalline phase in catalysts, indicating that Cu and Mg Co-Doping did not influence the crystal patterns of TiO2. Also, the DRS results indicated that the band gap of co-doped photo catalyst was smaller than that of the monometallic and un-doped TiO2 and there was a shift in the absorption band towards the visible light region. Discussion and Conclusion: The photocatalytic efficiency of the synthesized catalysts was evaluated by degradation of C. I. Acid Red 27under visible light irradiation. The results showed that Co-Doping of the Cu and Mg can significantly improve the photocatalytic activity of the prepared photo catalysts. The results showed that Cu (0. 1 wt. %), Mg (0. 06 wt. %) co-doped TiO2 with optimum calcination temperature 450 ° C had the highest photo activity among all samples under visible light. Additionally, the effect of influential parameters, such as doping content, photo catalyst dosage, initial dye concentration, initial pH and calcination temperature were studied.
