Application of FT-Raman spectroscopy to the study of the benzotriazole inhibition of acid copper corrosion
The initial stages of the corrosion protection of copper surfaces by benzotriazole in sulfuric acid solution are investigated using FT-Raman SERS and X-ray photoelectron spectroscopy. Spectra are measured in the presence of ppm levels of inhibitor on a copper surface in situ. The dependence of the adsorbate spectra on the electrode potential, solution pH, oxidation/reduction cycles and time is observed. Good spectra are obtained from copper electrodes prepared using in situ oxidation/reduction cycling in low pH sulfate solutions free from chloride at negative potentials.
