FTIR spectroscopic semi-quantification of iron phases: A new method to evaluate the protection ability index (PAI) of archaeological artefacts corrosion systems

Résumé

This study proposes an innovative approach to semi-quantify the main iron corrosion phases found in corrosion systems of archaeological artefacts. This method is based on the treatment of Fourier Transform Infrared Spectroscopy (FTIR) data using a homemade spectra decomposition software (PALME). Its application was first tested on mixtures of pure iron corrosion standards. After optimization, it was used to study real archaeological samples and evaluate the stability of their corrosion system. Considering that reliable and repetitive results were reached using extremely small quantities of material, this method can be particularly suitable for the study of iron-based objects of cultural interest.
