RESUMO
Different parameters were investigated to evaluate their effect on the process removal efficiency of reactive dye from simulated spent reactive dye bath, by solar / TiO[2] / H[2]O[2], including H[2]O[2] concentration, TiO[2] loading and pH. As a result 99% of reactive dye can be removed at a TiO[2] loading of 400mg/l, H[2]O[2] concentration of 150 mg/l and of pH: 5.2. The effect of photo-catalytic deactivation of TiO2 on reactive dye removal was studied for ten number of cycles, and found that the extent of deactivation was high for each consecutive repeated use
