Abstract

Mixtures containing tartrazine (TAN) and brilliant blue (BB) or patented blue (PB) were investigated in this work. The optimal pH for the simultaneous determination of these dyes is 1.5 and 7 (for pH=7: ε430(ТАN)=3.2·104, ε635(ТАN)=5.3·102, ε430(PB)=3.3·103, ε635(PB)=8.7·104; for pH=1.5: ε430(ТАN)=2.1·104, ε630(ТАN)=9.6·102, ε430(BB)=9.3·103, ε630(BB)=8.3·104). Classification models, that allow to identify mixtures containing TAN and BB, TAN and PB, chlorophyll and quinoline yellow with BB or PB, have been developed using methods of hierarchical cluster analysis, factor analysis (FA), partial least squares (PLS) and principal component analysis (PCA). Model solutions of dyes and 12 real objects (tarkhun, low-alcohol drinks, tonics and absinthe of various brands) were used for the classification. The best classification results were achieved at pH 1.5 using PLS and PCA. Quantitative models, based on the additivity of spectral signals and PLS, have been developed for determining the permittivity of these dyes in the simultaneous presence. In order to make it possible to analyse alcoholic drinks, the dependence of the molar attenuation coefficient on the dielectric conductivity of solvents was studied. The obtained regression equations were taken into account in the calibration for absorbance additivity. Methods for the quantitative determination of the investigated dyes were developed for the concentration range 0.2-2.0∙10-5 М.

化学计量法分光光度法同时测定酒黄石、专利蓝V和亮蓝FCF
本文研究了酒黄石(TAN)与亮蓝(BB)或专利蓝(PB)的混合物。同时测定这些染料的最佳pH分别为1.5和7 (pH=7时:ε430(ТАN)=3.2·104,ε635(ТАN)=5.3·102,ε430(PB)=3.3·103,ε635(PB)=8.7·104;pH = 1.5:ε430(ТАN) = 2.1 104·630年ε(ТАN) = 9.6·102年,ε430 (BB) = 9.3·103,ε630 (BB) = 8.3·104)。利用层次聚类分析、因子分析(FA)、偏最小二乘(PLS)和主成分分析(PCA)方法,建立了分类模型,可以识别含有TAN和BB、TAN和PB、叶绿素和含有BB或PB的喹啉黄的混合物。使用染料模型溶液和12种实物(tarkhun,低酒精饮料,滋补品和各种品牌的苦艾酒)进行分类。PLS和PCA在pH为1.5时分类效果最好。定量模型,基于光谱信号和PLS的可加性,已经开发用于确定这些染料在同时存在的介电常数。为了使分析酒精饮料成为可能,研究了溶剂的摩尔衰减系数与介质电导率的关系。将所得的回归方程用于吸光度可加性的标定。建立了所研究染料的定量测定方法,浓度范围为0.2-2.0∙10-5 М。
