Determine and compare the cmc point of SDS, Triton x-100 and CTAB surfactants using conductometery method



For years, surfactants or surface active substances have been considered scientists from different fields through their unique properties. They are working in different fields of application. One of the unique characteristics of these molecules is compounds called micelle. Determination the critical micelle concentration of surfactants (cmc) is necessary for the application of these compounds in various fields. There are many different methods for determination cmc point. In this research we used conductometery method for determining the cmc point of three Surfactants: Sodium Dodecyl Sulfate (SDS), Triton x-100 and cetyl tri methyl ammonium bromide (CTAB). Results have a good match with values presented in various scientific papers.
