With X-ray photoelectron spectroscopy apparatus and spectrophotometer, we investigated the changes in color and carbon valence of impregnated paper induced by ultraviolet irradiation. Results showed that in the process of ultraviolet irradiation on the macerated paper, there were three phases in its color variation, and the color in both ends changed strongly with green and yellow degree strengthening. The color changed little in the middle. Meanwhile, carbon valence also changed dramatically and high binding-energy content increased. According to its discoloration regularity, we deduced that the surface of impregnated paper had formed relatively stable "film" structure.%用X射线光电子能谱仪与分光光度计,分析浸渍纸受到紫外光辐照后,颜色及碳价态的变化情况.结果表明:浸渍纸在受到紫外光辐照过程中,颜色变化规律分3个阶段,两端变化大,且呈现黄蓝轴色品指数的增强,中间变化较小;同时,碳价态也发生了显著的改变,高结合能含量增加.结合其变色规律,推断出其表面形成了比较稳定的"膜"结构.
