“…1) corresponding to the reduction of the nitro-group up to amine, similar to reduction of these compounds on a mercury electrode [8,9]. The supporting electrolyte (HCl) is reduced on the CPE under more positive potentials (E=-0.8 V) in contrast to the mercury electrode, so the next peak currents are not seen.…”

“…This study reveals that the range of the reduction potential of substituted nitro aromatic compounds in acid pH is from 0.48 to 0.52 V, depending of the nature of the substituents. The sensibility of detection of para isomers with CPE is lower than for meta and ortho isomers in all cases studied [14]. Lin, Ni, and Kokot made a simultaneous determination of the noxious nitroaniline isomers, by cyclic voltammetry (CV) and DPV, with the electro-polymerization of 7-[(2,4-dihydroxy-5-carboxybenzene)azo]-8-hydroxyquinoline-5-sulfonic acid (DHCBAQS) at a graphene-nafion-modified GCE, denoted at this work as, DHCBAQS/graphenenafion/GCE.…”
