Abstract

The present work reports the voltammetric behavior of Zinc hexacyanoferrate (III) nanoparticles and their application in the detection of N-acetylcysteine. Two distinct ratios of water/formamide 10: 0 (ZnH-1) and 4: 6 (ZnH-2) were studied in the complexation reaction of Zn2+ with {[}Fe-III(CN)(6)](3-). The materials were characterized by Transmission Electron Microscopy (TEM) and Cyclic Voltammetry. The cyclic voltammograms of ZnH-1 and ZnH-2 showed a well-defined redox couple with formal potential (E-theta') = 0.94 +/- 0.01 V (nu=20 mVs(-1 ;) KCl 1.0 M)) attributed to the redox process {[}FeII(CN)6]/{[}FeIII(CN)6] in the presence of Zn2+. The graphite paste electrode modified with ZnH-1 and ZnH-2 presents a sensitive and catalytic oxidation response for the determination of N-acetylcysteine respectively. (AU)
