摘要
Cloud point property was found in the aqueous mixtures of sodium dodecyl sulfate（SDS）and cetyl trimethyl ammonium bromide（CTAB）and the cloud point area in pseudo ternary plase diagram of SDS/CTAB/Na2SO4/H2O was studied.It was found that the cloud point area was the aqueous two-phase system area,in which the containing of SDS was more than that of CTAB.The cloud point area would enlarge when the temperature was high and the length of cationic surfactant carbochain had some effect on the position of cloud point area.
