Abstract

By external reflection-absorption in situ FTIR spectroscopy, the generation of PbSO4 on Pb-electrodes in 5 M sulfuric acid was investigated. It was possible to monitor the process of lead sulphate formation (oxidation) during anodic polarization and of lead sulphate consumption (reduction) during cathodic polarization. A correlation exists between the electric charge passed through the lead electrode and the intensity of absorption bands of lead sulphate.
