A simple co-precipitation technique was developed to prepare SnO2 nanoparticles using stannous chloride dihydrate (SnCl2.2H2O) and characterized. The photocatalytic efficiency of nano SnO2 was tested for degradation of Naphthol blue black and conversion of Cr (VI) to Cr(III).In addition, mixture of chromium(VI) and Naphthol blue black (NBB) were selected as the dual dye system (model pollutants) and their influencing factors such as concentration of mixtures (Cr(VI) + NBB), catalyst dosage, intensity of light sources (254 and 365 nm), pH were also studied. Blank experiment (without catalyst) and surface adsorption indicates that NBB and Cr(VI) degrades at relatively low efficient respectively.
