Analytical Evaluation of Paper Degradation

Abstract

In this paper the object of study was to determine the chemical nature of foxing stains in paper. Purpose of the study: Was to deepen the knowledge on the paper with special emphasis on foxing stains, their chemical nature and morphological aspects of foxing stains. Methods used: Are photography under different illuminations and optical microscopy. The presence of fibers disruption was observed with (SEM-EDS), it was used also (ATR-FTIR). Micro X-ray diffraction was used to evaluate the crystalline fillers in the sample. Mass Spectrometry was used for chemical analysis to identify the organic components. Conclusion: Unfoxed and foxed areas of paper samples showed no differences from a morphological point of view. The sample’ surface was structurally organized, paper fibers seem to be in good condition, without any visible disturbance. The combination of several non-destructive techniques allowed the characterization of paper composition and the evaluation of morphological aspects.
