Abstract

Decolorization of blue azo dye (Cibacron Blue FN-R) in simulated wastewater has been investigated as a function of solar photocatalytic process. Different parameters that affected on the removal efficiency, such as initial concentration of dye, pH of the solution, catalysis dosage, and H2O2 concentration, were evaluated to find the optimal operation conditions. From the experimental results, the desired pH value for solar photocatalytic V2O5 was 2 and the best catalysis dosage was 500mg/L. In addition, the most efficient H2O2 concentration was 100 mg/L for V2O5. The mathematical models that describe the photocatalytic process have been predicted by using response surface methodology (RSM). The decolorization efficiency by using V2O5 as solar photocatalytic can be reached to 97%.
