内容記述 PEG is useful substance among any conservation materials, but it will be contaminants made of dead carbon for radiocarbon dating. Removal of PEG must be attempted to the conserved woods before radiocarbon dating. However, effective elimination methods of PEG from the conserved woods are not established yet. Therefore, we tested four treatment methods (AAA, +hot water, AAA+acetone, AAA +benzene) of the conserved woods to remove PEG. Radiocarbon dates of the treated samples were measured and compared with the true radiocarbon ages of samples to estimate efficiency of the PEG elimination. As the results, all radiocarbon dates of the treated samples were older than the true radiocamon ages, and it was revealed that any treatments could not eliminate PEG completely from the conserved woods. We also estimated the most effective elimination method of PEG through comparison of radiocarbon dates among the treated samples. Radiocarbon dates of samples treated by AAA + hot water method showed the nearest values to the true dates. Therefore, we speculated that the AAA + hot water method is the most effective treatment to eliminate PEG. On the other hand, in order to detect remaning PEG in the conserved woods, the wood samples were analyzed with PyGC/MS. Comparing with chromatograms between pure PEG and pure wood, characteristic peaks (C-n series) were observed for pure PEG but not for pure wood. Conserved woods with 4% remaining PEG were also analyzed by PyGC/MS, and the peaks of C-n series were observed on chromatograms. Thus we concluded that PEG remaining in the conserved woods can be detected using PyGC/MS definitely, and the detection of PEG with PyGC/MS will be help to measure accurate radiocarbon dates of woods conserved with PEG.
