摘 要:为快速排查纺织助剂中烷基酚聚氧乙烯醚(APEO),建立了红外光谱对纺织助剂中APEO的定性和定量方法.应用红外二阶导数谱图中(1 608±4)cm-、(1 510±3) cm-1处一组特征吸收峰筛查纺织助剂中不同分子结构形式的APEO.红外光谱对APEO的定性方法不需标准品,不需对样品进行分离,简单快速.同时,应用定量软件TQ Analyst中的偏最小二乘法,选择二阶导数红外光谱并选取(1 529.27~1 496.45 cm-1)峰范围建立APEO定量模型,回归系数为0.999 46,均方根误差为0.970.应用该定量模型对APEO定量,结果显示其绝对偏差在-1.56%~3.18%范围,回收率在82% ~ 117%之间.For rapid detection of APEO in textile auxiliaries,a method for qualitative and quantitative analysis of APEO by infrared spectroscopy was developed.Using a couple of characteristic absorption peaks of (1 608 ± 4) cm-1 and (1 510 ± 3) cm-1 in the second derivative infrared spectrum,APEOs which were in different molecular structure form in textile auxiliaries could be detected.The method is simple and fast,in which standard reagents of APEOs are not necessary and the different components in samples needn't to be separated.Besides,applying the method of least squares in the quantitative software of TQ Analyst,and using the second derivative infrared spectrum and selecting peak range from 1 529.27 cm-1 to 1 496.45 cm-1,quantitative model for APEO was established.In this quantitative model,the regression coefficient R and RMSEC (root mean square error contrast) were 0.999 46 and 0.970 separately.The results of quantitative analysis for APEO in textile auxiliaries showed that their absolute deviations were in the range of-1.56%-3.18% and the recovery rates of APEO were about 82%-117%.
