3.Scaning electron microscopy and cyclic voltammetry are applied to characterize both the physical and chemical properties of the Ag ring ultramicroelectrode.
4.Scaning electron microscopy and cyclic voltammetry are applied to characterize both the physical and chemical properties of the Au ring ultramicroelectrode.
5.We developed a new method to determine critical micella concentration of anionic surfactant by adsorption voltammetry, using neutral red, as a probe.
