| 摘 要： | 采用电导法及表面张力法分别测定了十二烷基硫酸钠(阴离子表面活性剂)和十二烷基三甲基氯化铵(阳离子表面活性剂)的临界胶束浓度,两种实验方法测得十二烷基硫酸钠的临界胶束浓度约为7.0×10-3mol·dm-3,十二烷基三甲基氯化铵的临界胶束浓度约为1.60×10-2mol·dm-3,两种方法所得结果一致。

| Abstract: | Critical micelle concentration of two surfactants was determined by conductometric method and surface tension method.The experiment result showed that the critical micelle concentration of sodium dodecyl sulphate was 7.0 × 10 -3 mol · dm -3 and the critical micelle concentration of twelve alkyl three methyl ammonium chloride was 1.60 × 10 -2 mol· dm -3.The results of the two methods for the determination had the same results. |
