Rose Bengal (RB) was intended to be degraded by the use of photo catalysis process which is proposed to be mediated by ZnO and irradiated under ultraviolet light. The absorbance measurement was used to estimate degradation efficiency. The catalytic activity was studied with the condition of dye concentration, photocatalyst loading capacity, pH of dye solution, irradiation time and temperature. The progress of the reaction was observed spectrophotometrically at 547 nm. In addition, the kinetics of the degradation dye was examined and the degradation was found to follow first order kinetic model at 547 nm. It was found that the dye degradation gave the best results at a pH of 9, and with 0.05 g/dm3 ZnO. At room temperature, the photocatalytic degradation rate constant of RB dye was k = 0.0282 min-1.
