| 摘 要： | 用紫外分光光度法对苯胺、联苯胺和α-萘胺进行直接测定,用化学计量学中的主成分分析法、偏最小二乘法和径向人工神经网络方法对数据进行处理.波长范围为200~310 nm,隔1 nm采集数据.方法操作简单,无需过多的分离即可消除常见干扰物的影响,3种苯胺类化合物的相对标准偏差分别为5.91%、6.82%和3.40%.

| Abstract: | Several chemometric methods including partial least squares, principal component regression and artifical neural network was applied to the determination of aniline, benzidine and 1-naphthylamine. The spectrophotometric data between 200 nm and 310 nm were collected at 1 nm intervals. The optimum conditions for the determination of each component were evaluated and the method was employed to the analysis of synthetic and real environmental samples. The best relative predictive errors are 5.91% ,6.82% and 3.40% , respectively. |
