摘要
在翡翠的漂白、酸碱蚀、蜡质物和高分子聚合物注入等项实验研究的基础上,利用傅立叶变换红外光谱仪,重点对蜡质物和高分子聚合物充填处理翡翠的红外吸收光谱进行表征.结果表明,利用2 800～3 000 cm-1范围内由蜡质物和高分子聚合物(CH2和CH3官能团)致红外吸收谱带的相对吸收比(Ra)和其半峰宽面积(Sa),可以对翡翠的优化与处理尺度进行判定,即:1/4＜Ra≤2/4,Sa≤15(无需标识);2/4＜Ra≤3/4,15＜Sa≤30(为'优化');3/4＜Ra≤4/4,30＜Sa(为'处理').对翡翠的漂白、漂白充填处理和酸碱蚀充填处理的本质与属性予以了剖析.
Based on the experimental studies on characteristics of the bleached, alkali-acid corroded,wax and macromolecule polymer-filled jadeite jade,the infrared absorption spectra of wax and macromolecule polymer-filled jadeite jade are studied by using Fourier transform infrared spectrometry. The results indicate that the relative absorptance（Ra ）of the infrared absorption band and half apex-breadth area （Sa）are closely associated with the absorption of CH2 and CH3 in wax and macromolecule polymer,and usually can give enough evidence for scale determination of enhancement or treatment of jadeite jade, namely： 1/4〈Ra 42/4, Sa≤15（dispensing with label）and 2/4〈Ra≤3/4,15〈Sa≤30（enhancement）and 3/4〈Ra≤4/4, 30〈Sa （treatment）. The essence and attribute of the bleached waxed jadeite jade and alkaliacid corroded filled jadeite jade are analyzed primarily in the paper.
