Assessment of the Stability of a Mercury Film on a Glass–Ceramic Carbon Electrode when Determining Zinc in the Presence of Manganese by Anodic Stripping Voltammetry

The possibility of assessing the stability of operation of a mercury film graphite electrode in anodic stripping voltammetry using Shewhart control charts (CCs) is shown. The offered technique allows significantly increasing the efficiency of the voltammetric determination of zinc and manganese and...

Summary:The possibility of assessing the stability of operation of a mercury film graphite electrode in anodic stripping voltammetry using Shewhart control charts (CCs) is shown. The offered technique allows significantly increasing the efficiency of the voltammetric determination of zinc and manganese and taking measurements of analytes in samples during a working day without replacing the mercury film on the electrode surface.
