摘要
制备了Span80-Tween80/异辛烷/AM-H2O反相微乳液体系,用电导法考察了不同HLB(亲水-亲油平衡)值下电导率的变化规律,并研究了正丁醇(n_butanol)、氯化钠(NaCl)和醋酸钠(NaAc)的加入对微乳液体系电导率变化的影响规律。实验表明:HLB值为5.4时体系的电导率变化较小。正丁醇质量浓度为25g/L时电导率几乎没有变化,当NaCl质量浓度为50g/L或NaAc质量浓度为25g/L时可以增加体系的稳定性,为检测微乳液的稳定性提供了一种有效途径。
A study was conducted to examine the varying regularity of conductance of the reverse microemulˉsion of Span80-Tween80/isooctane/AM-H 2 O at different hydrophilic-lipophilic balance(HLB)values by conductometry.The effects of n_butanol,NaCl and NaAc on the variations of conductance properties were disˉcussed.The results showed thatthe conductance was relativelysmall when the HLB approached5.4.The conˉductance remained constant in25g/L n_butanol,but the stability was enhanced by adding50g/L NaCl or25g/L NaAc into the system.
