Abstract

The co-oxides Cr2O3-NiO was prepared by using a co-precipitation method. The co-oxides were prepared by calcination temperatures at 500 ºC. The prepared materials were investigated using powder X-rays diffraction and Fourier transform infrared spectroscopy. The photocatalytic activity of prepared co-oxides was examined by removing Bismarck brown G dye from simulated industrial wastewaters. From the obtained results, the best efficiency for Bismarck brown G dye removal was found to be around 97. 5 %. This was achieved at optimal reaction conditions which were pH = 4, weight of catalyst 0.15 g, T = 303 K and time of reaction was 1 h. Both of Frundlich and Langmuir adsorption isotherms were studied.
