Effect of operating parameters on microwave assisted photocatalytic degradation of azo dye X-3B with grain TiO2 catalyst

The photocatalytic decomposition of azo dye X-3B was investigated in microwave assisted photocatalysis with microwave electrodeless lamp as light source (MWL/TiO2). A novel grain TiO2 (GT01) had been used as catalyst, which was easily separated from water. The effect of different operating parameters on photocatalytic oxidation was discussed. Moreover, influence of microwave irradiation on effect of operating parameters was investigated.
