Rezumat: The electrochemical behavior of the [Cu2(DH)4γ,γ-bipy], (where DH is the monoanion of α,α’-dimethylglyoxime and γ,γ-bipy represents 4,4’-dipyridyl) was investigated for the first time by cyclic voltammetry and stripping cathodic voltammetry on the mercury drop electrode. The influence of some experimental parameters (pH, scan rate, concentration and electrolytic medium) on the electrochemical behavior of the complex has been examined as well. It has been established that the electrochemical reduction of [Cu2(DH)4γ,γ-bipy] is an adsorption controlled and irreversible process. The linear dependence of cathodic peak current and the concentration of [Cu2(DH)4γ,γ-bipy] has been elucidated. Keywords: cooper complexes, α,α’- dimethylglyoxime, 4,4’-dipyridyl, stripping voltammetry, cyclic voltammetry |
