The electrode area is normally in the range of 0.1 to 0.5 cm2 and mercury film thickness typically ranges from 10 to 1000 nm, producing a film of large surface area-to-volume ratio that results in a high analyte pre-concentration during the deposition step of anodic stripping voltammetry. Compared to an HMDE, the MFE provides high sensitivity and resolution; however, it is somewhat less reproducible and more prone to interferences from intermetallic formation and surface-active substances.@en"] [2,"smw-datavalue-wikipage-property-invalid-title","HasComment","Liquid mercury is an ideal electrode material for negative potentials because of its high overpotential for hydrogen evolution (electrochemical reduction of hydroxonium cations from solution). However, mercury is readily oxidized, particularly in the presence of anions that form complexes or that pre- cipitate with Hg(I) or Hg(II) ions, and thus it is not suitable for use at positive potentials. The use of liquid mercury has largely been discontinued because of concerns about the toxicity of the element and its compounds.@en"] OSWdf78745ef9db483088f08ce074fcb8ff# ERR0cf8c53d7c740a4d5c6eafb6f7e19495 DroppingMercuryElectrode 14 en OSWb76a778f253f4210a67ffb6444d0de26 SubClassOf 102 en SubClassOf
