The reduction of nickel dimethylglyoxime complex preadsorbed on mercury
The voltammetric reduction of NiII(DMGH)2 complex preadsorbed on mercury both in 1 M NH4Cl + NH3 buffer and in 0.1 M borate buffer solutions was studied. In this work experimental evidence points to NiII(DMGH)2 reduction with simultaneous decomposition of the ligand DMGH- and reduction of Ni(II) to...

| Sumario: | The voltammetric reduction of NiII(DMGH)2 complex preadsorbed on mercury both in 1 M NH4Cl + NH3 buffer and in 0.1 M borate buffer solutions was studied. In this work experimental evidence points to NiII(DMGH)2 reduction with simultaneous decomposition of the ligand DMGH- and reduction of Ni(II) to Ni(O). The experimental sweep rate dependence of peak current and potential is explained in terms of a ErCi surface reaction scheme and a rate expression that takes into account attractive forces between the adsorbed reactant complex. © 1997 Elsevier Science S.A. |
