摘要/Abstract

摘要： 针对常规同时测定法存在测定周期长且对于多峰吸光度曲线不适用的问题,提出一种改进的同时测定法测定混合染液中各组分的浓度。首先运用高斯逼近法拟合固定浓度下各单一染液的吸光度、波长的模型。然后根据朗伯-比尔定律推导出各单一染液的吸光度、波长与浓度的模型,并给出了求混合染液各组分含量的具体步骤。最后以3种活性染料的混合染液浓度测定说明算法的可行性和有效性。

关键词: 改进同时测定法, 高斯逼近法, 吸光度模型

Abstract: For long determination period and inapplicable for the multi-peak absorbance curve of conventional simultaneous determination,an improved simultaneous determination method is proposed to determine individual dye concentrations in the mixed reactive dye liquors.Firstly,using the Gaussian approximation method fitting the model of fixed concentration of a single dye absorbance and wavelength. Secondly,the model of single dye absorbance,wavelength and concentration were derived according to the Lambert-Beer Law.The specific steps of the algorithm is provided to determine individual dye concentrations in the mixed reactive dye Liquors.At last,the individual dye concentrations determined results show that the effectiveness and efficiency of the proposed scheme.

Key words: improved simultaneous determination, Gaussian approximation method, absorbance model
