Decolorization of simulated spent reactive dye bath using solar / TiO^sub 2^ / H^sub 2^O^sub 2

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^sub 2^ / H^sub 2^O^sub 2^, including H^sub 2^O^sub 2^ concentration, TiO^sub 2^ loading and pH. As a result 99% of reactive dye can...

Summary: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^sub 2^ / H^sub 2^O^sub 2^, including H^sub 2^O^sub 2^ concentration, TiO^sub 2^ loading and pH. As a result 99% of reactive dye can be removed at a TiO^sub 2^ loading of 400mg/l, H^sub 2^O^sub 2^ concentration of 150 mg/l and of pH: 5.2. The effect of photo-catalytic deactivation of TiO^sub 2^ 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.
