Abstract: This paper describes a voltammetric study of cadmium nitroprusside synthesized from different compositions of water/formamide in your reaction of Cd2+ with [FeIII(CN)5NO]2- (CdNP). After infrared and transmission electron microscopy characterization, the CdNP was incorporated into a carbon paste electrode and a systematic voltammetric study was performed for four systems (CdNP-1, CdNP-2, CdNP-3 and CdNP-4). The spectroscopic studies reveals that all preparations was conducted with success. The cyclic voltammogram of all CdNP particles obtained from a carbon paste electrode modified (10% m/m) exhibited a redox couple with formal potential (E'teta'')=0.63 ± 0.02 V (10 % (m/m); v=20 mV s-1; KNO3 1.0 M)) attributed to the redox process [FeII(CN)5NO]/[FeIII(CN)5NO] in the presence of Cd2+.
