| Abstract: | The results obtained from the measurements of cotmterion association degree using ion selective electrode with improved experiment techinique and equation for CTMAB micelle system are in accordance with that calculated by electrochemical theory of micelle. The study also show that the externally added KBr concentration have no effects on the counterion association degree of thecelle and KBr are unnecessary for the determination of counterion association degree in the CTMAB concentration rannge of Ct<4CMC. Addition of hexanol decreases counterion association degree in CTMAB micelle systems. |
