摘要：博物馆文物环境因装饰材料所致甲醛污染以及由此产生对文物危害问题已被普遍关注。为了评价净化材料实际使用中对污染物去除净化能力,搭建了静态试验舱,建立了该环境中甲醛的定量分析方法。研究了甲醛溶液法和人造板散发法两种产生甲醛气体的方法,以及吸附材料不同加入方法等对净化材料评价结果的影响,研究试验舱内甲醛浓度随时间的变化规律,建立了净化材料脱附量检测方法,分别测定了活性炭和三种壳聚糖基净化材料的净化效果。结果表明,用人造板散发法产生甲醛气体方法能用于甲醛净化材料的评价,得到净化率指标反映了净化材料在实际文物环境中的应用效果,脱附量指标能直观比对和反映净化材料对污染物的吸附稳定性。
Formaldehyde pollution from decoration materials may damage the museum objects on display,which is widely concerned.In order to evaluate the effectiveness of formaldehyde removal by absorbent materials,a closed test chamber was set up and the formaldehyde concentration in the chamber was measured.Formaldehyde was generated from solution or synthetic board,various absorbents were added and a formaldehyde concentration vs.time curve in the chamber was recorded.An evaluation method was established.Active charcoal and three chitosan-based absorbents were tested for their ability to remove formaldehyde.This work showed that air purification studies are best done with formaldehyde generated from synthetic board,which better reflects the true situation in museum environments.The absorb stability of absorbents could be used to compare and reflect the stability of absorbents.
