摘　　要：为了探索鉴定古代文物彩绘胶料的综合分析方法,使用红外光谱仪及氨基酸分析仪对中国古代五种常用文物彩绘胶料的红外吸收光谱及氨基酸组成进行了测定。通过对样品红外光谱特征吸收峰的判别、分析,得出了1653cm-1及1545cm-1处的吸收峰为蛋白类胶料的特征,1076cm-1及1043cm-1处的吸收峰为桃胶的特征,以及奶类同时具有蛋白类胶料及桃胶特征的结果。通过对样品氨基酸组成的分析,得出了动物胶特有羟脯氨酸及较多的甘氨酸,鸡蛋含有较高的天冬氨酸和较低的脯氨酸,奶类的谷氨酸和丙氨酸含量比较高的结果。研究结果表明,通过氨基酸分析结合红外光谱的特征吸收峰,可以基本区分、判定古代文物彩绘常用胶料归属的结论。FTIR and amino acid analysis were used to characterize five commonly used binding media found in ancient cultural relics.According to the FTIR spectra,characteristic of protein based binders are the peaks around 1653cm-1 and 1545cm-1;peach gum has peaks around 1076cm-1 and 1043cm-1;casein shows peak characteristic of both protein based binder and peach gum.Amino acid analysis of animal glue shows,uniquely,hydroxyproline and a high level of glycine.Eggs have a higher content of aspartic acid and lower proline.And casein has a higher content of glutamic acid and alanine.It is conclude that based on their amino acid composition and their FTIR characteristics,commonly used ancient binding media can be differentiated and identified.
