Alternated current voltammetry as a means of heavy metal ions sensitivity determination increase by stripping voltammetry calibrationless method

The alternated current version of stripping voltammetry determination of heavy metal ions in aqueous solutions, which does not require pre-calibration with standard solutions, was proposed. The detection limits of cadmium (II) and mercury (II) ions in direct current and alternated current modes of measurement on mercury graphite (MGFE) and gold graphite (GGFE) film electrodes respectively were calculated.
