Magdalena Śliwka-Kaszyńska, Ph.D., D.Sc. Eng.

The area of research is related to the archaeological chemistry and archeometry. Research activity is focused on the isolation and identification of natural organic colouring substances from various types of matrices, including: dyeing raw materials, historical artistic paints and fabrics. Systematic research on photodegradation processes of dyes is carried out in order to determine the possible routes of their decomposition and to determine their degradation products. The influence of taphonomic processes (body decomposition, bioerosion) on the state of preservation of colouring substances is also analysed, which is necessary for the correct understanding of their "aging" processes that directly affect the change of the initial colour. Investigations are performed using liquid chromatography coupled with a UV-Vis detector and a mass spectrometer (ESI-MS and QTOF).
