Degradation of Bisphenol A by TiO_2 Photocatalysis Assisted with Three-dimensional Electric Field

The TiO2/Ti film electrode was prepared by sol-gel method.A photocatalytic degradation reactor assisted with three-dimensional electrode was designed and applied to degrade bisphenol A(BPA).The results show that the degradation efficiency of BPA by TiO2 photocatalysis assisted with three-dimensional electric field is good,and the degradation rate of BPA reaches 100% after 120 min.The optimal anode bias is 8 V under this experimental condition.Increasing conductivity is beneficial for degradation of BPA when the conductivity is smaller,but the degradation rate of BPA decreases with the increasing of conductivity when the conductivity is larger.The degradation of BPA accords with apparent first order reaction.
