Dye Concentrations Determination in Ternary Mixture Solution by Using Colorimetric Algorithm

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 new method is compared with that of Beer’s law evaluated at three wavelengths, and Beer’s law evaluated at ۱۶ 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 ۵۵.۶۴%, ۱۲.۳% and ۱۴.۸۴% respectively for new test solutions. Its average ternary relative error is ۱۱.۶۸% which is comparable to ۱۴.۳۱% for Beer’s law at three wavelengths.
