Article: Impedance spectroscopy analysis in a complex system: Sodium dodecyl sulfate solutions
[show abstract] [hide abstract]
ABSTRACT: Impedance measurements in the range 10–107Hz were carried out in water solutions of sodium dodecyl sulfate for concentrations below and above critical micellar concentration (cmc). The results were analysed using a series combination of two Voigt units, describing bulk and interface process and, additionally, an unexpected inductive one, problably due to inertial effects of an adsorbed layer of SDS molecules at the electrode. The interface processes, including the inductive one, show transition at a concentration somewhat below cmc.Journal of Sol-Gel Science and Technology 04/2012; 38(2):191-195. · 1.63 Impact Factor
