硝基苯类化合物的岭回归──可见分光光度法同时测定

Simultaneous Determination of Nitrobenzenes with Ridge Regression Spectrophotometry

摘要: 根据萘乙二胺与硝基苯类发生偶合显色反应而生成有不同颜色的稳定配合物的特点,测定了水中硝基苯类混合体系的吸收光谱,结合聚类分析、因子分析和岭回归技术对合成水样中硝基苯、对硝基甲苯、间硝基甲苯、对硝基氯苯、2,4-二硝基氯苯等多组分硝基苯的光谱数据进行解析,成功地确定了合成水样中硝基苯类的物种数及各物种的含量.

Abstract: Based on that N-(1-Naphthyl)-aethylendiamin-dihydrochlorid can reaction with nitrobenes to form a magenta, the spectra data are analyzed by mathematical methods to optimize the wavelengths, and to determine the number of multicomponents, the quantity of each species as well as the concentrations of every compound involved.
