CMC OF ALKYLAMMONIUM NITRATE DETERMINED BY A NOVEL METHOD

A novel method for the determination of the critical concentration of a micelle formation based on the measurement of liquid junction potent ial was presented in this paper. The CMC values of the typical anionic and cationic surfactants and the new compounds, alkylammonium nitrate s were obtained by using the method. The CMC values of the new compoun ds were confirmed by means of the conventional methods. In addition, t he transport numbers of those compounds relating to the dynamic behavi or in solution were estimated and the physical meaning was discussed.
