Mihailciuc %J Analele Universitatii Bucuresti : Chimie %D 2008 %I %X Using consecutive cyclic voltammetry (CV), cobalt (II) hexacyanoferrate (CoHCF) and cobalt (II) hexacyanoferrate/poly (3-methyl thiophene) (CoHCF/P3MT) films have been prepared in fresh solutions formed between CoCl2 1mM, K3[Fe(CN)6] 0.5 mM and KCl 0.5 M for the Pt/CoHCF electrode and DMSO as a solvent, TBAPF6 0.1M and 3MT 50mM for the Pt/P3MT/CoHCF electrode. Then, using different cyclic voltammetry techniques, chemically modified electrodes, Pt/CoHCF and Pt/P3MT/CoHCF, were used to study their response in a phosphate buffer system of 7.2 pH and in ascorbic acid of various concentrations. %U http://gw-chimie.math.unibuc.ro/anunivch/2008-2/AUBCh2008XVII20712.pdf
