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.
