The organic pollutant methyl violet dye photocatalytic degradation has been investigated using the UV irradiation and TiO 2 as a catalyst. The degradation process included the study of the initial dye concentration, light intensity, catalyst weight, the effect of intensity of light, and effect of temperature to approach the best conditions for the optimum photo-degradation efficiency of dye. The optimum photocatalytic degradation of methyl violet dye was at 0.15 g/100cm 3 of dosage mass of TiO 2 and 10 ppm of the dye. Photocatalytic degradation of methyl violet dye was at 9 mW/cm 2 light intensity. The percentage efficiency of degradation methyl violet dye equals 97.46%.
