摘　　要：分别应用914 cm^(-1)和875 cm^(-1)处的甲基特征峰作为叔丁醇和二叔丁基过氧化物的定量分析峰,使用峰面积作为吸光度的评估方法,得到的标准曲线的相关系数(R^(2))分别是0.9987和0.9952,叔丁醇的加标回收率在95%~110%之间,应用衰减全反射傅里叶变换红外光谱法测定3个样品,计算结果的F值、t值和p值,数据表明衰减全反射傅里叶变换红外光谱法与气相色谱法的测定结果一致。The characteristic peaks of methyl at 914 cm^(-1)and 875 cm^(-1)were used as quantitative peaks of tert-butanol and di-tert-butyl peroxide, respectively. At the same time, peak areas were used as the indicators of absorbance. The correlation coefficients(R^(2)) of the standard curves for tert-butanol and di-tert-butyl peroxide were 0.9987 and 0.9952, respectively. The recovery rate of tert-butanol was from 95% to 110%. Three samples were determined by attenuated total reflectance Fourier transform infrared spectrometry and the F, t and p values of the results were calculated. The results obtained by attenuation total reflectance Fourier transform infrared spectroscopy were consistent with those by gas chromatography.
