摘要
分析了天然及优化处理祖母绿的红外光谱鉴别特征。使用显微放大观察确定有无充填裂隙,确定位置后,再用红外光谱仪检测,确定充填物的种类。通过对11件祖母绿样品及四种充填常用的油和胶的分析,确定了红外光谱3034cm-1、3053cm-1属环氧树脂的特征峰,可作为判定祖母绿优化还是处理的重要鉴定依据。红外光谱可以较为准确地区分油和胶,比起目前常用的显微镜观察鉴定更为准确和可靠。
This article was mainly about the identification feature of natural, optimized and treated emerald by FTIR. First, microscope was used to ensure the fissures with filler or not, then we used FTIR to test the ensured position to confirm the type of fillers. After analyzing 11 emerald samples and 4 common used oil and glue, we ascertain that the peak 3034 cm^-1, 3053 cm^-1 of infrared spectrum was caused by cpoxide resin, and this can be an important evidence of filling, Infrared spectrum can distinguish oil and glue accurately, and was a useful tool to identify treatment.
