摘要
本文采用主成份分析法处理钨、钼、锡、钛-苯基萤光酮-CTMAB体系的吸光度数据,建立了主成份分析法完成多组份体系定量分析的数学模型。
The principal component analysis(PCA) method for simultaneous determination of components in mixtures is developed and described. In this method, a mathematical model is obtained from a set of samples of known composition and is then used to predict the contents of unknown samples. This method is practically applied to the simultaneous determination of Tungsten, molybdenum, tin and titanium in mixture with chromogentic reagent phenylfluorone in the presence of cetyltrimethylammonium bromide.
