Abstract: The photocatalytic degradation of direct red 31 on irradiation with UV light in the presence of ZnS photocatalyst has been reported. Effect of pH, weight of catalyst and concentration of dye on the degradation has been studied. A higher removal of dye is observed under mildly acidic conditions. The optimum weight of catalyst loading is found to be 3.0 g/L. The dye degradation obeys first order kinetics and is explained on the basis of Langmuir-Hinshelwood mechanism.
