摘要: 为快速排查纺织助剂中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1608±4cm-1, 1510±3 cm-1一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(1529.27cm-1,1496.45cm-1)峰范围建立APEO定量模型,回归系数R为0.99946,均方根误差RMSEC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, 回收率为82~117%。

Abstract: For the rapid detection of APEO in textile auxiliaries, methods for qualitative and quantitative of APEO by infrared spectra analysis were developed. Using a couple of characteristic absorption peak of 1608 ± 4cm-1, 1510 ± 3 cm-1 in the second derivative infrared spectrum, APEOs which were in different molecular structures forms in textile auxiliaries could be detected. The methods were simple and feasible, in which standard reagents of APEOs were 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 1529.27cm-1 to 1496.45cm-1, quantitative model for APEO was established. In this quantitative model, the regression coefficient R and RMSEC (Root Mean Square Error Contrast) were 0.99946 and 0.970 separately. The results of quantitative for APEO in textile auxiliaries showed that their absolute deviations were in range of -1.56~3.18% and the recovery rates of APEO were about 82~117% .

Key words: infrared spectrum, second derivative spectrum, APEO, characteristic absorption peak, textile auxiliaries
