摘要
Abstract
The content of Irganox 3 114 in polypropylene was quantitatively analyzed by Fourier-transform infrared(FT-IR)spectroscopy,and its characteristic absorption peak was determined at 1 695 cm-1.Meanwhile,the FTIR spectrum shows a quantitative absorption peak for PP at 4 059 cm-1 through comparing the infrared spectral information of Irganox 3114,PP,and PP/Irganox 3114 blend.By taking 1/A4059 as the thickness standardization factor,A1695/A4059 as the hori-zontal coordinate,and 3114 content as the vertical coordinate,the standard curve of Irganox 3114 was established.The results indicated that the content of Irganox 3114 had a good linear relationship with A1695/A4059,and its linear correlation coefficient was 0.999 28.The effect of thickness standardization factor was verified,and the sample thickness had no in-fluence on the determination result of the content of Irganox 3114 over the experimental range.The relative standard de-viation of this method is less than 1.30%for the determination of Irganox 3114,and its precision is good.The absolute relative error of Irganox 3114 in standard substance is less than 3.27%,and the accuracy of this method is higher.关键词
