The anodic oxidation of mercury in the presence of methane-1,1-bis-mercaptoacetic acid (MBMA) has been studied by DCr, DP, AC1, and AC2 polarography, cyclic voltammetry, and coulometry. The electrode process is controlled by the adsorption of the product formed according to: Hg + 2 H(2-n)Ln- → H(2-n)HgL2n- + (2-n) H+ + 2e with n = 0 at pH < pK1, n = 1 at pK1 < pH < pK2, and n = 2 at pH > pK2. No adsorption of MBMA is observed. The behaviour of MBMA at a hanging mercury drop electrode (HMDE) by cathodic stripping voltammetry (CSV) has been also studied. At MBMA concentrations above 1 10-6 mol l-1, the stripping voltammograms showed two well defined peaks, at c. -0.140 V and at c. -0.300 V. The anodic process occurring during the pre-electrolysis in CSV is described by the formation of a Hg(I) compound: 2 Hg + 2 H(2-n)Ln- → H(2-n)Hg2L2(2-2n)+ + 2e followed by its disproportionation: H(2-n)Hg2L2(2-2n)+ →c H(2-n)HgL2(2-2n)+ + Hg,where n has the above-mentioned values.

AbstractUsing the method of cyclic voltammetry, the electrode process of Ni2+, Pb2+, Cu2+ and pyrocatechin on a poly(o-aminophenol) (PoAP) modified glassy carbon electrode (GCE) was investigated. The PoAP polymer was found to affect the redox process of copper and pyrocatechin. The use of polymer of different thicknesses showed that the obtained film has a dense, nonporous structure. The redox process of the examined substances may be considered as proceeding on the polymer surface. The PoAP polymer obtained in the described conditions takes part in charge transfer.
