Abstract
The fluorescence characteristics of I-5/I-1, and I-3/I-1 of pyrene whi ch is sensitive to the environment of probe was used to study the crit ical micelle concentration(cmc) of N-dodecylbetaine and N-tetradecylbe taine. The effect of salt concentration on the cmc values was studied. Tile results obtained indicate that cmc values determined from the pa rameters I-5/I-1, of pyrene are close to that from the surface tension measurements, and more accurate than that from I-3/I-1.
