Decolorization of simulated spent reactive dye bath using solar / TiO2 / H2O2
Journal Title: International Journal of Environmental Science and Technology - Year 2005, Vol 2, Issue 3
Abstract
Different parameters were investigated to evaluate their effect on the process removal efficiency of reactive dye from simulated spent reactive dye bath, by solar / TiO2 / H2O2, including H2O2 concentration, TiO2 loading and pH. As a result 99% of reactive dye can be removed at a TiO2 loading of 400mg/l, H2O2 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.
