摘要

Removing solid lipids with surfactants in an aqueous solution is observed with a quartz crystal microbalance. The pH of the bathing solution is adjusted to 7.0―12.0 at 25 and 30℃. Concentrations of four anionic and nonionic surfactants vary from far below the CMC to ten times the CMC. The alkalinity of the solution at pH 9.0―12.0 causes swelling of the lipids by about 10%, but adding surfactants results in swelling up to 10―20%, followed by lipid removal by solubilization. This removal takes place at concentrations lower than the CMC. From this fact and the dependence on surfactant concentration of the removal rates by the two kinds of surfactants, we can infer that micelles of anionic surfactants do not participate in the removal, while those of nonionic surfactants do participate.
