摘要:The fluorescence characteristics of I-5/I-1, and I-3/I-1 of pyrene which is sensitive to the environment of probe was used to study the critical micelle concentration(cmc) of N-dodecylbetaine and N-tetradecylbetaine. The effect of salt concentration on the cmc values was studied. The results obtained indicate that cmc values determined from the parameters 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.
