Anodic Stripping Polarography

Post‐Transition Metal Electrodes for Sensing Heavy Metal Ions by Stripping Voltammetry

“…Subsequently, the oxidizing response of M n+ is promoted (Equation ( 6)) by the previous amalgamation, which enhances the enrichment of HMIs on the surface of electrodes. [40] However, the formation of intermetallic compounds still represents a challenge for multi-HMIs detections. Intermetallic compounds were reported to influence the HMIs detection.…”

Anodic Stripping Voltammetric Determination of Cd and Pb with Nanocarbon Film Electrode Fabricated by Unbalanced Magnetron Sputtering

“…5,6 Various electrode materials have been employed for ASV measurements. In the past, a mercury electrode [7][8][9][10] was preferred for ASV because it forms an amalgam with various metals and has a low noise current in the cathodic potential range. However, it is now recommended that mercury not be used in the construction of commercial analysis systems because of its high toxicity.…”

Increased sensitivity of anodic stripping voltammetry at the hanging mercury drop electrode by ultracathodic deposition

“…(1) (deposition step) ascribes the electrolytic accumulation of the analyte in the working electrode under controlled conditions [9]. The deposition potential to be applied varies with several factors including type of analyte, solvent and pH, among others; however, in ASV, the common rule is the application of a potential around 300 mV more negative than the peak potential of the least easily reduced analyte to be analyzed.…”
