摘要

The dimensional stable lead electrodes modified by sodium dodecyl sulfate (SDS) were prepared with electrochemical deposition and it shows that a more compact, uniform, and smooth film of Ti/PbO2(F+SDS) electrode reduces the corroded crystal faces and surface defects. Characterization results demonstrate that the oxygen evolution potential (OEP) of the Ti/PbO2(F+SDS) electrode was higher, and its service life is almost 1.6 times longer than the Ti/PbO2(F) electrode. Compared with Ti/PbO2(F) electrode, the soluble Pb concentration of the Ti/PbO2(F+SDS) electrode decreased 15.1%, which indicates that the decrease of crystal surface defects leads to the reduction of Pb ions so that the excellent corrosion resistance electrodes cause low environmental risks. The modified electrodes were used as anodes to degrading bisphenol A (BPA) when an electrolyte is 0.2 M Na2SO4, the applied voltage is 5 V and electrodes distance is 3 cm, 20 mg/L BPA for electrolysis time of 180 min can reach up to 97.6%.
