Dye Concentrations Determination in Ternary Mixture Solution by Using Colorimetric Algorithm

Abstract

This publication uses a colorimetric method based on the absorbance spectra of dye solutions to improve on Beer's law when calculating the dye concentrations of a three-component mixture. The performance of the n ew method is compared with that of Beer's law evaluated at three wavelengths, and Beer's law evaluated at 16 wavelengths. Colorimetric method gives the best prediction of dye concentrations: the average relative errors in its predictions of the blue, red, and yellow concentrations are 55.64%, 12.3% and 14.84% respectively for new test solutions. Its average ternary relative error is 11.68% which is comparable to 14.31% for Beer's law at three wavelengths.
