红外光谱测定2,6-二叔丁基对甲酚检测限的研究

Study on Detection Limit of 2,6-di-tert-butyl-4-methylphenol by Infrared Spectrum

文章介绍了傅立叶变换红外光谱仪测定润滑油中抗氧剂2,6-二叔丁基对甲酚(T501)的含量,考察不同光程长的液体池对抗氧剂T501最低检测限的影响,同时确定抗氧剂T501的最低检测限:光程长为3 mm时,抗氧剂T501的最低检测限最低,达到0. 01%(质量分数),相关系数为0. 9984。

The detection limit of 2,6-di-tert-butyl-4-methylphenol determined by Fourier Transform Infrared Spectrometer was introduced in this paper. The effect of liquid pool with different optical path length on the minimum detection limit of antioxidant(T501)was investigated,the minimum detection limit of antioxidant(T501) was determined. When the optical path length is 3 mm,the lowest detection limit of antioxidant(T501) is 0. 01%(mass fraction),and the correlation coefficient is 0. 9984.
