摘要：

The formation of Triton X-100 reverse micelles and water in oil microemulsions in mixed solvents of benzene/n-hexane was observed and the aggregates were investigated by dynamic light scattering and turbidity measurements. The apparent hydrodynamic diameter D(h) of the aggregates is a function of the benzene/n-hexane ratio, surfactant concentration, water content, and the concentration of salt (CaCl2), if present. At low water content, CaCl2 is distributed in the polar core of the aggregates. The presence of CaCl2 enhances the capacity of the aggregates to solubilize water, and decreases D(h). With increasing water content, once aqueous pools are formed, the solubility of CaCl2 is greatly enhanced and additional amounts of the salt are solubilized in the pools.
