| 摘 要： | 敦煌莫高窟壁画盐害主要来源于可溶性盐(NaCl和Na<,2>SO4)与水的相互作用.本文依据沉淀电导滴定原理,建立了一种用于分析莫高窟壁画地仗中Cl-和SO2-4离子含量的方法,对比研究了莫高窟第98窟地仗坚硬处和地仗酥碱处可溶盐阴离子含量,并与离子色谱分析结果进行了比较.实验结果表明,该方法简便快捷,可用于莫高窟壁画地仗可溶盐的现场快速分析.

| Abstract: | Salt harm to the wall-paintings in Mogao Grottoes is mainly derived from the interaction of soluble salts(NaCl and Na2SO4)and water.This article developed a rapid method for on-site analysis of chloride and sulfate ions in plaster ground for the wall-paintings by conductometric titration.A comparative study was performed to investigate the contents of soluble salts at different sites of Cave 98 Mogao Grottoes,and it is found that the salt content in efflorescence of wall-paintings was higher,which is consis... |
