Abstract

A simple and sensitive spectrophotometric method was developed for determination of ternary mixtures catechol (CT), hydroquinone (HQ) and resorcinol (RS) without previous separation. The method is based on mean centering of second ratio spectra. The mathematical explanation of the procedure is illustrated. The method was evaluated by determination CT, HQ and RS in synthetic ternary mixtures. The procedure was successfully applied to the simultaneous determination of these analytes in water samples.
