摘要: 在对混合物样品的紫外可见光谱测量数据阵矩进行主成分分析、潜变量投影等方法解析后,得到一种物质的光谱曲线和另一种物质的动力学曲线,这在化学计量学意义上是一类比较特殊的黑色体系.提出了一种解析这个难题的算法,并详细论证了方法中不可避免的唯一解问题.对于模拟数据,解析结果证明本算法的正确性.用本法解析了苯胺水溶液电解过程,得到苯胺和中间物的动力学曲线及其纯光谱.

Abstract: In this paper using a variety of chemometrics methods such as PCA(Principle component analysis), HELP(Heuristic evolving latent projections), GA(Genetic algorithm) on the data matrix of the UV Vis spectra of mixture samples, we obtain the UV-Vis spectrum of one substance and the dynamic curve of another substance. We design a set of regressions to analyze this black system, and demonstrate in detail the unavoidable problem of the unique solution. With the simulated data the analytical results prove the correctness and accuracy of the regression. Finally a preliminary study was made on the electrolytic process of aniline, in which the UV-Vis spectra and the dynamic curves of aniline and intermediale are calculated.
