| 摘 要： | 考察阴离子表面活性剂十二烷基硫酸钠（SDS）和阳离子表面活性剂十六烷基三甲基溴化铵（CTAB）混合体系的表面张力和乳化能力,并研究无机盐对混合体系性能的影响。实验结果显示,当m（SDS）：m（CTAB）为8：2时,表面张力低至29.25mN·m^-1,表现出较强的表面活性,且无机盐有降低表面张力的作用。表面活性剂混合体系对煤油具有较好的乳化能力。

| Abstract: | The surface tension and emulsifying ability of the mixed system of anionic surfactant sodium dodecyl sulfate（SDS） and cationic surfactant cetyl trimethyl ammonium bromide（CTAB） are studied,and the influencing of the inorganic salt on the mixed system is researched.The results show that the surface tension reachs 29.25mN·m-1 when the mass ratio of SDS to CTAB is 8：2,which show good surface activity.It also could be concluded that the inorganic salt will reduce the surface tension.And the mixed system has a better emulsifying ability to the kerosene. |
