Abstract:
An ultrasound‐enhanced electrochemical oxidation process with boron‐doped diamond anodes is adopted and used for removing bisphenol A. The reaction activity and mechanism is evaluated and explained through experimental and theoretical methods. The structure and stability of the anode surface are illustrated and the electrochemical oxidation channels leading to ⋅OH formation are proposed using density functional calculations. Ultrasound increases the diffusion and mass transfer of ⋅OH at a high working potential (i.e., 3.0 V), while enhancing the collision frequency between organic pollutants and *O radicals at low working potentials (i.e., 1.7 V). The main intermediates determined by HPLC are hydroquinone, maleic and oxalic acids in both processes, suggesting the same degradation pathway even with ultrasound.
