| Abstract | ||
| In the present study, the effect of process parameters on photocatalytic degradation Bismarck brown Y dye has been examined in a batch reactor under UV light in heterogeneous slurry utilizing various concentrations of different semiconductors commercial catalysts (TiO2 , ZnO , CdS and ZnS). Parameters has been studied (catalyst type, catalyst concentration , pH of dye solution and dye concentration at the beginning). The results show that the best values of TiO2 , ZnO , CdS and ZnS are 1 , 0.5 , 1.25 , 1 g/l respectively and the optimum pH are (10 , 6 , 8 and 10) using TiO2 , ZnO , CdS and ZnS respectively. Moreover the comparative assessment of the photocatalytic efficiency was made for different photocatalytic powder. It was noticed that the best photocatalytic efficiency as ZnO > TiO2 > ZnS > CdS respectively. The percentage removal of chemical oxygen demand (COD) of the dye solutions was higher than that of the degradation of dye for the same conditions of catalyst. | ||
