LUDMILA MOTELICA, LUMINITA CRACIUN, IOANA ARDELEAN, MADALINA VIOLETA IOANA NON-DESTRUCTIVE ANALYSES OF 16TH CENTURY DOCUMENTS
The aim of the present study was to obtain spectral data (FTIR, UV-Vis and fluorescence) from five paper specimens taken from documents made between 1517-1609 that are in the custody of Carol I”Central University Library. The samples were chosen in an effort to characterize and better understand the paper composition and origin in order to have more information to enable comparison and identification with documents from same period. Gelatine content, cellulose type, crystallinity index, degradation degree and presence of calcium (as alkaline reserve) were determined by UV-Vis, FTIR and fluorescence spectrometry.
