Ratio Derivative Spectrophotometric Study of Binary Mixture of Dye Solution

Abstract

In this work, new method was used for prediction the concentration of binary mixture of textile dyes by using spectrophotometric data. New method is based on ratio derivative spectra of dyes mixtures solution. The obtained results by this method have been compared with usual spectroscopy methods. In special mixture with overlap spectra such as red and yellow mixtures, the derivative method was better than normal spectroscopy method.
