초록

Electrochemistry of 1.0 mM tris(2,2'-bipyridyl)ruthenium(II) ($Ru(bpy)_3{^{2+}}$) in 300 mM $H_2SO_4$ solution with and without sodium dodecyl sulfate (SDS) is studied. In the presence of SDS, $E_{pa}$ of $Ru(bpy)_3{^{2+}}$ shifts to positive direction compared to the SDS free case. The intersection of two lines on ${\Delta}E_p$ vs. -log[SDS] plot is measured as a critical micelle concentration (CMC), which is 3.67 mM SDS.
