Popis:	Cyclic voltammetry method was used to investigate the dispersal behaviors of micelles in mixed solutions of cationic surfactant CTAB (cetyltrimethyl ammonium bromide) and anionic surfactant SDS (sodium dodecyl sulfate) at 313 K using ferrocene as the probe. Voltammetric behaviors of ferrocene on the electrode were reversible, indicating the diffusion of ferrocene in the mixtures of cationic and anionic surfactants was controlled by the microstructures of the mixtures. The results showed that the anionic micellar diffusion coefficient initially decreased and then increased with CTAB content due to the structural transformation of micelles. However, the cationic micellar diffusion coefficient curve appeared a monotonous decreasing trend with the increase of the CTAB content in the experimental range, and the diffusion coefficient of cationic micelle was smaller than that of anionic micelle.
