摘要

制备了AOT[二(2-乙基己基)磺化琥珀酸钠]/异辛烷/水反相微乳液

用电导法研究了体系的增溶性质及其电导行为

对反相微乳液滴的有效半径进行了理论计算.根据电导率σ的CFM(ChargeF luctuation M ode l

CFM)模型

从理论上求算了-σR关系

并将结果与采用CFM模型的预测结果进行了对比.结果表明:AOT/异辛烷溶液对水的增溶能力随着AOT在异辛烷溶液中浓度的增大而提高.温度对增溶能力的影响比较大

且存在一个最佳温度

即在25℃时的增溶能力最强.AOT/异辛烷/水反相微乳液滴的有效半径Re先随R的增大而减小

达到极小值后则随R的增大而增加.在精确求算反相微乳液分子结构参数的基础上

采用电导率σ的CFM模型来预测反相微乳液体系的电导是切实可行的.

Abstract

The reverse microemulsion system of AOT/isooctane/H2O was prepared

and the regular changes of their solubilization ability and electrical conductance were researched by conductivity method.The effective radius of reverse microemulsion droplet and the σ-R relation were researched following CFM(charging fluctuation model).The result shows that the solubilization of AOT/isooctane to H2O is increased with the concentration of AOT in isooctane

and the influence of temperature is very important for solubilization.The solubilization ability is reached to the optimal state when temperature is at 25 ℃.The effective radius of droplet of reverse microemulsion Re is decreased with the increasing of R

but is increased with the increasing of R after reaching its minimum.The electrical conductance predicted by CFM on the basis of knowing the molecule structural parameter of reverse microemulsion was feasible.
