Cathodic stripping voltammetry

  "id": "MLC-T-CHM-001740",
  "term": "Cathodic stripping voltammetry",
  "field": "Chemistry",
  "definition": "An electrochemical technique for quantitative analysis where the analyte is first accumulated on the working electrode by oxidation at a controlled positive potential. Following this preconcentration step, the potential is scanned in the negative (cathodic) direction. This scan causes the deposited species to be reduced and stripped from the electrode surface, generating a current peak whose magnitude is proportional to the initial analyte concentration.",
