摘要：

A direct spectrophotometric method for the simultaneous determination of Thymol Blue, Semi-Methylthymol Blue (SMTB) and Methylthymol Blue (MTB) in mixtures in the presence of other components usually found in synthetic SMTB and commercial MTB is presented. The method for selecting the most advantageous conditions for the spectrophotometric determination of the three dyes in different mixtures is given. A graphical version of the method is useful for monitoring syntheses of SMTB and MTB.
