Research ArticleOpen accessIn the abstractDetermination of A.C. Impedance Spectroscopic and Cyclic Voltammetric Behavior of Some Heterocarbonyl Compounds in Both Aprotic and Aqueous MediaFarouk A. RashwanThe electrochemical behavior of eosin, isatin and alloxan in aqueous KNO3 and NaClO4 solutions on the Hanging Mercury Drop Electrode [HMDE] and in aprotic DMF and CH3CN on the Pt-disk electrode at 298 K was investigated using the Cyclic Voltammetry (CV) and the Electrochemical Impedance Techniques (EIS). In the CV experiment, the electroreduction of eosin in both aqueous and non-aqueous … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,665 accessesView PDF Cite
