Popis:	Impedance measurements in the range 10-10/sup 7/ Hz were carried out in solutions of sodium dodecyl sulfate for concentrations below and above cmc. The results were analysed using two series 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 show a transition at a concentration somewhat below cmc.
