摘要：

The effect of replacing the Na+ counterion of Aerosol OT by Cu2+ On the hydration mechanism of AOT reverse micelles was studied by infrared spectroscopy. The IR properties of ternary systems formed by Cu(AOT)(2)/[H2O]/CCl4 are reported and compared with the corresponding Na(AOT) system. The results show significant differences in interactions of Na+ and Cu2+ counterions with H2O molecules and the SO3- headgroup of AOT.
