•Cathodic Stripping Voltametry (Fe, Co, Ni, Zn, Cu)
–Hanging Mercury Drop Electrode (CSV-HMDE)
–Preconcentrates using adsorption of a metal-Lsynthetic complex
–Reduces the metal (and in some cases the ligand) to generate signal
•e.g. -0.6V to -1.4 V
•Anodic Stripping Voltametry (Zn, Cd, Pb)
–Thin Film Mercury Rotating disk electrodes (ASV TF-RDE)
–Preconcentrates using adsorption of elemental metal holding a reductionpotential
–No synthetic Ligand needed
–Oxidizes the metal to achieve signal
•e.g. -1.4 to -0.4 V
