Voltammetric study of complex formation in systems "nickel (II), cobalt (II), – eriochrome black T"
The laws of surface complexation and the equilibrium in the electrode layer systems "nickel (II), cobalt (II) - Eriochrome Black T" was studied by voltammetry method at the dropping mercury electrode. Values of the effective stability constants of complexes of nickel (II) and cobalt (II) with Eriochrom Black T were found. The adsorption laws and kinetic characteristics of the electrode process were studied. The influence of various factors on the catalytic current systems "nickel (II), cobalt (II) - Eriochrome Black T" was studied. The mechanism of electrocatalytic processes in the system "nickel (II), cobalt (II) - Eriochrome Black T" was proposed.
