Abstract

A spectrophotometric method for simultaneous determination of dyes has been developed. It is based on the resolution of a mixed spectrum over an appropriate wavelength range, by applying a least‐squares fitting program to standard spectra for each component. The proposed method was applied to mixtures of 1:2 metal‐complex dyes typically used by the leather industry. Four dyes were quantified simultaneously in less than a minute, with overall errors less than 2.5% © 1995 Society of Dyers and Colourists
