Influence of metal cations on leather degradation
Original language description
Ions of transition metals (mainly iron or copper) occurs a heavy damage in historical leathers. These ions are contained in pigments or they come from chemicals used for leather marbling or from direct contact of leather with metal clips etc. After accelerated ageing of samples the influence of transition metal cations was evaluated by determination of changes in mechanical properties, pH value and shrinking temperatures. Structural changes were examined by means of scanning electron microscope. SDS-PAGE electrophoresis and spectroscopy of electron paramagnetic resonance. In leather samples a semiquinone radical has been detected, which initiates their oxidation. The transition metal cations catalyse this oxidation process thus increasing the damage extent when compared to leathers not containing these ions.
