The electrochemical behaviour of the nickel(II) ion at the dropping mercury electrode in the presence of some complexing agents — II

Interaction of niacin with nickel(II) ions

“…The reduction potential of this species is nearly 0.29 V more positive than that of the Ni(II) aquaion, and is close to that obtained for the other Ni(II) complexes with N-coordinated ligands inducing prewave [31,[43][44][45][46][47][48][49], but differ significantly from values reported by Banica (À0.78 V) [29] and Cakir (À0.94 V) [30]. It should be noted that Cakir et al [30] performed their experiments in ammonium tartrate solution (at pH ca.…”

Kinetic and electrochemical analysis of Ni(II) reduction at the dropping mercury electrode in the presence of thiourea

“…Agganval and Crow (36) have studied the electrochemical behaviour of the Ni2+ species at the DME for several complexing ligands. Heterocyclic ligands share a common feature that their reduction involves two electrons.…”
