Abstract:This study focuses on the Qing Dynasty printed edition of "Tong Jian Ji Shi Ben Mo" collected by the National Museum of China. Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS), Macro X-ray Fluorescence (MA-XRF), Laser Confocal Micro Raman Spectrometer (Raman), Fourier Transform Infrared Spectroscopy (FTIR), and Solid Phase Microextraction-Arrow Gas Chromatography/Mass Spectrometry (SPME Arrow-GC/MS) were utilized to investigate the inorganic elements, chemical structure, ink composition, and emitted gas components of the ancient books. The results show that the inorganic elements of the ancient book"s paper are mainly Ca, S, and K, which are enriched at the tide line; the ink pigment is pinewood soot; the condition of the protective pages is relatively good, with no significant oxidation. A non-targeted screening of the gases emitted from the paper identified 58 compounds, including aging products of the paper as well as substances adsorbed during use and historical preservation, forming the "old book smell" of the ancient book. These findings provide scientific evidence for understanding the preservation status of " Tong Jian Ji Shi Ben Mo " and formulating appropriate restoration plans. The non-destructive and minimally destructive analytical methods used in this study show promising applications in the research of paper-based cultural relics. |
