Abstract: 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(R_a) of the infrared absorption band and half apex-breadth area(S_a) 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＜R_a≤2/4,S_a≤15(dispensing with label) and 2/4＜R_a≤3/4,15＜S_a≤30(enhancement) and 3/4＜R_a≤4/4,30＜S_a(treatment). The essence and attribute of the bleached waxed jadeite jade and alkali-acid corroded filled jadeite jade are analyzed primarily in the paper.
