Raman and Infrared Spectroscopy of Aqueous Corrosion Films on Lead.

Abstract

The use of Raman and infrared spectroscopy to analyze surface films on metals is described. Surface films formed on lead by reaction with aqueous buffer solutions were examined. The composition of each film was determined by Raman spectroscopy while the sample was in the solution. Multiple reflection infrared spectra of dry samples confirmed the Raman results. The Pourbaix diagrams for lead in water with and without chloride were calculated and potentiostatic exposures were conducted to see if the compounds correspond to those predicted in the diagram. Tetragonal PbO was found to occur over a much greater range of potentials than thermodynamic stability would indicate. Several differences due to the presence of chlorides were noted. (Author)
