摘要：

Kinetic studies of cationic surfactant uptake in an anionic polymer network have been performed, varying the species of co-ions of the surfactant and counterions of the charged network. It was found that the rate of surfactant uptake is distinctly dependent on both the counterions and co-ions which could be explained in terms of the ion pair diffusion mechanism associated with their mobilities in the network. A simple linear relation between the surfactant flux and the harmonic mean of the molar mobilities of the surfactant ion, its co-ion, and the network counterion has been established experimentally.
