Abstract :
The dye, acid blue 113, was degraded photo catalytically by using ZnO nano particles under visible light irradiation in a continuous flow reactor. ZnO nano particles were synthesized by Sol-gel process and it was characterized by SEM, EDX, XRD, and BET analysis. The prepared ZnO nano particles were effectively used for the photo degradation of acid blue 113. The effect of various operational parameters such as pH, concentration and flow rate was carried out. It was found that the maximum dye degradation occurred at 50 μM at pH 7. The optimum flow rate was observed at 11.7 ml/min for 2g of the catalyst.
