Cobalt(II) ion was determined by inversion-voltammetric method using a carbon paste electrode modified with tropeolin.Optimum conditions for creating a modified electrode were found, according to which the ratio of paraffin, graphite, tropeolinwas 1:1:0.025. Complex formation of cobalt with sodium salt of 4-(4-anilinophenylazo)-benzosulfonic acid (Tropeolin00) wasdetermined by cyclic voltammetry (SV) method. A universal buffer pH 2.58 solution was used as the optimal environment for theformation of a complex of Co (II) ion. The results were compared with those obtained based on a platinum electrode.
