Abstract: | A common nonionic surfactant Triton X-100 was dissolved in a commercial ionic liquid (IL) 1-butyl-3-methylimidazolium tetrafluoroborate (bmimBF4). The surface tension of the bmimBF4 solution was decreased with increasing the content of surfactant Triton X-100, a similar phenomenon with aqueous solution systems. Dynamic surface properties of Triton X-100 in bmimBF4 were measured. It was found that pure IL solvents need rearrangement at the air-bmimBF4 interface during the beginning stage of absorption. Moreover, the adsorption model was found to be in accord with the diffusion-controlled adsorption mechanism, and further, the dilute bmimBF4 solutions are close to the diffusion-controlled adsorption. |
