Simultaneous spectrophotometric determination of o-cresol red, semi-xylenol orange and xylenol orange.
A direct simultaneous spectrophotometric method for the determination of o-Cresol Red (CR), Semi-Xylenol Orange (SXO) and Xylenol Orange (XO) in mixtures in the presence of other components usually found in commercial SXO and XO reagents is presented. The method of selecting the most advantageous conditions for the spectrophotometric determination of the three dyes in different mixtures is given.
