探讨了十六烷基三甲基溴化铵（CTMAB）、十二烷基硫酸钠（SDS）和TritonX-1003种胶束对酸碱指示剂百里香酚蓝和溴百里香酚蓝离解反应的离解常数的影响，进而研究了以上3种胶束对指示剂变色点和变色范围的影响，实验结果表明，选择适当的胶束溶液作为滴定介质，不仅可以扩大酸碱指示剂的应用范围，而且还大大提高了测量的准确度。

The effect of cetyltrimethylammonium bromide (CTMAB), sodiumdodecyl sulfate(SDS) and poly(oxyethylene)(9.5) p-(1,1,3,3-tetramethyl) (Triton X-100) on the dissociation constants of thymol blue and thymol blue bromide, and the color-changing point and color-changing range were studied. The experimental results indicated that the application range of acid-base indicators became wider and the titration accuracy was increased when an appropriate surfactant micellar solution was chosen as a titration medium.
