Abstract
Electrical conductivity has been measured for decylammonium chloride a nd cesium perfluorooctanoate aqueous solutions over a range of concent rations from 0-50 wt.% using an alternating field with frequencies fro m 0.1-20 kHz at 20, 30, 40 and 50 degrees C. From the results the crit ical micelle concentration and free energy of micellization have been discussed and compared with the literature data. Also, the activation energy has been evaluated from conductivity results at various tempera tures. Considerable differences were found between the activation ener gy at low and high concentrations for both systems.
