                         boron doped diamond (BDD) electrode was studied in 
                         Britton-Robinson (BR) buffer using cyclic voltammetry. NFZ was 
                         directly reduced to the amine derivative (RNH2) in the pH range of 
                         2.0 to 4.0 in a process involving six (6.0 +/- 0.4) electrons and 
                         six protons. In the range of pH 7.0 to 12 and. predominantly 
                         aqueous medium, the reduction step split into its two components: 
                         the reduction of NFZ to the to hydroxylamine derivative (RNHOH) in 
                         processes involving one radical anion (RNO2.-) and reduction of 
                         RNO2.- and three (3.1 +/- 0.1) electrons, respectively. On the 
                         anodic scan of the voltammograms and at pH 8.0, the oxidation of 
                         the hydroxylamine to the nitroso derivative (RNO), was observed in 
                         a process involving 2 (1.7 +/- 0.2) electrons and 2 protons. In 
                         addition and unreported in the literature on any electrode 
                         material, was the detection of a new oxidation peak at pH > 8.0.

                         reduced or not. The calculation of n, number of electrons, 
                         involved in each electrochemical step was satisfactorily 
                         accomplished using the Randles-Sevcik equation.",
