| 摘 要： | 在25℃时利用电导法测定了添加剂甲醇、乙醇、丙醇、PEG、β-环糊精和NaOH对十二烷基苯磺酸钠(SDBS)溶液的临界胶束浓度的影响。实验结果表明,随着甲醇、乙醇、丙醇、PEG、NaOH加入量的增加,均使SDBS溶液的cmc值降低;不同分子量的PEG对SDBS溶液cmc值的影响是相同体积分数的PEG200

| Abstract: | The effect of additives(methanol,ethanol,propyl alcohol,PEG,β-cyclodextrin,NaOH) on the critical micelle concentration of sodium dodecyl benzene sulfonate(SDBS) has been studied by using conductivity method at 25 ℃.The experiment results indicate that the cmc of SDBS solution decrease with increasing additives such as methanol,ethanol,propyl alcohol,PEG and NaOH.PEG200 and PEG400 with the same volume proportion have the different effects on the cmc which are in the order of PEG200
