河北鸡泽墓葬壁画表面污染物光谱研究

The Spectrum Study of The Surface Pollutants on The Tomb Wall Paintings at Jize County,Hebei Province

邯郸市鸡泽县考古工地发掘出土了三座宋金墓葬,墓葬内壁绘制有壁画,壁画表面覆盖大面积黑色物质,利用红外和拉曼光谱分析,红外特征峰位3382 cm^(-1)、1756 cm^(-1)、1633 cm^(-1)、1393 cm^(-1)、1000 cm^(-1)、869 cm^(-1)和腐殖酸的特征吸收峰接近,综合两种光谱分析结果,判断该物质为腐殖酸。腐殖酸的产生需要潮湿、缺氧、酸性条件,其与鸡泽县的地理位置、墓室的密闭性和酸性微环境等、古代丧葬习俗等因素均有关系。

Three Song or Jin Dynasties tombs were unearthed at the archaeological site in Jize County,Handan City.Wall paintings were painted on the inner wall of the tombs,and the surface was covered with a large area of black material.The infrared characteristic peaks of 3382 cm^(-1),1756 cm^(-1),1633 cm^(-1),1393 cm^(-1),1000 cm^(-1),869 cm^(-1)were similar to the characteristic absorption peak of humic acid,synthesize the two spectral analysis results,it could be judged to humic acid.The production of humic acid required moist,anoxic and acidic conditions,which were related to the geographical location of Jize County,the tightness of the burial chamber,the acidic micro-environment and the ancient burial customs.
