چکیده

This paper deals with the comparison of the Cr (III) dopant from tannery wastewater to the Cr (III) from the pure salt solution on the character and activity of TiO₂. The doping was conducted by hydrothermal method, and the Cr-doped TiO₂ prepared was characterized by UV specular reflectance (SRUV), X-ray diffraction (XRD), and X-ray fluorescence instruments. The effect of the Cr (III) doping on the activity of the TiO₂ was evaluated by Congo red photodegradation. The research results reveal that Cr (III) doping on TiO₂ has been successfully reducing remarkably the band gap energy (Eg) from 3.13 eV to 2.64 eV, shifting into the visible region, and further noticeably improving TiO₂ activity. The effect of the Cr (III) doping from the wastewater is found to be slightly higher than that of the salt solution. The highest degradation of 10 mg/L Congo red in 50 mL solution, can be reached by applying 30 mg of the photocatalyst in 60 mins and at pH 7.
