摘要
In this work, a dual flow-through heterogeneous electrochemical system was proposed in which a porous Ti/SnO2-Sb membrane and graphite felt (GF) were used as anode and cathode, respectively. By combining of anodic oxidation (AO) and electro-Fenton (EF), this electrochemical system obtained a synergism effect on organic pollutants degradation resulted in a high removal efficiency. In addition,attributed to the application of dual flow-through mode, mass transfer was improved which is also beneficial for organic pollutants degradation. The results illustrated that this dual flow-through electrochemical system exhibited a brilliant treatment performance for BPA wastewater treatment. It can be observed that the dual flow-through electrochemical system owned a removal efficiency of 99.2% under optimum condition (2.5 V voltage at pH=3 using 0.05 M Na2SO4 as electrolyte). The mechanism investigation results indicated that the good treatment performance was due to the ·OH generated from both EF and AO processes and O2-· produced through AO process. In addition, this dual flow-through electrochemical system also exhibited a good reusability and application. It reveals a potential for factual wastewater application.
