摘要：
In work the electrochemical behaviour of copper(II) in dimethylsulphoxide solutions of copper nitrate (II) is investigated. The electroreduction of the complex ions of copper(II) of the composition. Cu(MCO)(4)(H2O)(2)](2+) is proceeding in two-stage on the adsorbate molecules of organic solvent electrode. The main kinetic parameters (coefficients of transfer (alpha), heterogeneous constant of velosity (k(s)) and effective energy of activation (A((sic)phi))) of process electroreduction of the ions copper(II) in dimethylsulphoxide, witnessing about quasireversible of process were determined. The general velosity of cathodic process brakes of more slow second stage, having the mixed nature of control, as compared with stage transfer of first electron was shown.
