Determination of Hg(II) ion by inversion voltammetric method using graphite electrode modified with anthranilic acid

Pollution of the environment with heavy metals, including mercury, poses a serious environmental hazard. Its determination, even in microconcentrations, is relevant. Purpose. Determination of Hg(II) ions by voltammetric method on a graphite electrode modified with anthranilic acid. Methodology. The object of the study is anthranilic acid and Hg(II) ions. The stripping voltammetric method for their analysis was used. Originality. A graphite electrode modified with anthranilic acid for the selective determination of Hg(II) by voltammetric method was used for the first time. Findings. Voltametric characteristics of the cathodic behavior of Hg(II) ions in the background electrolyte, with buffer solutions, at different pH, for different periods of electrolysis were recorded.
