本文建立了衰减全反射傅里叶红外光谱法(ATR-FTIR)定量分析柴油燃料中脂肪酸甲酯含量的方法。在实验条件下,标准曲线的线性相关系数为0.9998,精密度相对标准偏差为0.5%~2.3%,准确度相对偏差绝对值在5%以内。该方法简便、快速,能够满足柴油燃料中脂肪酸甲酯含量分析的要求。

A method used to detect the content of fatty acid methyl ester in diesel fuel oil by attenuated total reflection fourier transform infrared spectroscopy(ATR-FTIR) was established. Under the experiment conditions, the linear correlation coefficient of the standard curve was 0.9998, the relative standard deviations of precision were between 0.5% and 2.3%, and the relative standard deviations of accuracy were all within 5%. This simple, rapid and environmentally friendly method can meet the requirements for detection of fatty acid methyl ester content in diesel fuel oil.
