100 mM NaCl+27 mM <TEX>$MgCl_2$</TEX> 용액에서, 도데실황산나트륨 (SDS)의 유무에 따른 1.0 mM 메틸비올로겐 (<TEX>$MV^{2+}$</TEX>)의 전기화학적 거동을 연구하였다. <TEX>${\Delta}E_p$</TEX>(산화와 환원 봉우리전위 값의 차이) 대 - log[SDS]로 도시한 그림에서 두 선의 교차점을 임계미셀농도 (CMC)로 결정하였다. <TEX>$Mg^{2+}$</TEX>가 첨가되면, 유리탄소전극에 대한 효과적인 <TEX>$MV{\cdot}^+$</TEX>의 접근이 가능해지고 미셀형성도 지연되었다.
Electrochemical behaviours on 1.0 mM methylviologen (<TEX>$MV^{2+}$</TEX>) in 100 mM NaCl+27 mM <TEX>$MgCl_2$</TEX> solution, without and with sodium dodecyl sulfate (SDS), were studied. The intersection of two lines on <TEX>${\Delta}E_p$</TEX> (the difference between the anodic, <TEX>$E_{pa}$</TEX>, and the cathodic, <TEX>$E_{pc}$</TEX>, peak potentials) of the first and second redox waves vs. -log[SDS] plot was determined as a critical micelle concentration (CMC). When <TEX>$Mg^{2+}$</TEX> was added, the effective access of <TEX>$MV{\cdot}^+$</TEX> to the glassy carbon electrode surface became possible and the formation of micelles was retarded.
