| Abstract: | The effect of different temperature and the addition of organic alcohol and inorganic salts on the CMC of CTAB are discussed by means of bromide ion selective electrode.The CMC of CTAB assumes the weak trend of increase along with the increasing of temperature,and reduced along with the lengthening of carbon chain in organic alcohol,and reduced remarkably along with the increasing of the charges of anoin in inorganic salts. |
