Abstract

When a hydrophobic and hydrophilic environments of bis(2,2'-bipyridyl) copper(II) ($Cu(bpy)_2{^{2+}}$) are produced in the presence of anionic surfactant sodium dodecyl sulfate (SDS), cyclic voltammetry is used to investigate the microscopic environments which occurs at the glassy carbon electrode. In order to see the relation between ${\Delta}E_p$ and a critical micelle concentration (CMC), ${\Delta}E_p$ vs. -Log[SDS] for the redox couples are plotted. The concentration at the intersection of two lines is 2.57 mM SDS, and this concentration can be determined as the CMC (relative error: below 0.03%; 2.63 mM SDS by surface tensiometry).
