【摘要】 研究了电导率测定微乳液的最大增溶水量及最大增溶水量的影响因素。以Span80和Tween80为复配表面活性剂,正辛烷作为油相,在超声波作用下制备微乳液;利用电导率仪测定微乳液的电导率,利用Original lab绘图软件对得到的电导率作图,通过曲线的突变点来确定微乳液的最大增溶水量。亲水亲油平衡值(HLB)和表面活性剂浓度是微乳液最大增溶水量的两个主要影响因素,通过研究它们的变化对最大增溶水量的影响,我们得出了较佳的微乳液最大增溶水量。更多还原

【Abstract】 The most water solubilizing capacity in microemulsion and influencing factors were studied in this paper.Using span80 and Tween80 as complicated surfactant and using octane as oil phase,Microemulsion was prepared with the action of the ultrasonic.The conductance of microemulsion was measured with the conductance apparatus.Then the graph by ploting with the Original lab software was gained and the most water solubilizing capacity in the breakpoint of the curve was confirmed.There were two important factors that affected the most water solubilizing capacity: HLB and the concentration of surfactant.By studying the factors,the better result was gained.更多还原
