| 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. |
