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.展开更多
