摘要
以延安革命纪念馆馆藏的20世纪三、四十年代图书等纸质文献为材料,设计了其释放气体的提取工艺,并采用气质联用仪(GC-MS)对其释放的气体进行了检测分析。分析结果显示:纸质文献及无任何字迹的纸张释放的气体中均含有乙酸,由此可推测出乙酸来自于长久保存的纸质文献纸张中纤维素的降解;纸质文献在保存过程中除了保证馆内通风良好、控制好温湿度等条件外,采用能够有效吸附纸质文献释放气体的特藏装具也可以延长纸质文献保存寿命。
The gases released from the books of Yan′an Revolutionary Memorial Hall were extracted and analyzed by GC-MS.Results indicate that acetic acid gas was detected in paperbased archives with or without writing due to the degraclation of paper cellulose.In preservation of paper-based archives,some methods to adsorb gases released from archives are efficient to extend life of archives even in optimal temperature and humidity.It is proposed that the life of the acchives can be extended by using the container which can absorb the released gases.
