Removal of Alizarin Yellow dye from water using zinc doped WO3 catalyst.
The degradation of Alizarin Yellow dye is studied here using the laser-induced photo-catalysis process in the presence of a zinc doped tungsten oxide catalyst. For optimization of the photo-catalytic process, the following parameters were investigated: dye concentration, laser irradiation time and incident laser energy. The calculated value of the reaction rate was found to be of a high value (k) = 0.197 (with estimated half-life of 6.5 min). This high value of k indicates the efficiency of this method in removing Alizarin Yellow dye from wastewater.
