Cathodic stripping voltammetry — Refers to a family of procedures involving a - preconcentration by electrochemical oxidation (or reduction) of the analyte (or a salt or derivative of the analyte) onto (or into) the working electrode prior to its direct or indirect determination by means of an electroanalytical technique (see also -> stripping voltammetry, and - anodic stripping voltammetry) [i]. During the stripping step, i.e.,... 

Mercuric and mercurous salts — Salts of Hg(II) and Hg(I), respectively. Soluble mercuric and mercurous salts such as acetates and nitrates are used for the deposition of mercury films on conducting substrates (see -> anodic stripping voltammetry). Insoluble salts, e.g., chloride and sulfate of Hg(I) in chloride and sulfate medium, respectively, can be used to prepare reference electrodes (see -> calomel electrode). The formation of insoluble salts of mercury on - mercury electrodes determines, among others, the positive limit of their voltam-metric potential window. 

Other versatile and sensitive techniques for determination of metal ions in water are atomic absorption, which uses the attenuation of a beam of light of the appropriate wavelength by the atomized metal as the measure of concentration, and anodic stripping voltammetry, which is an electrochemical technique. Eurther details of all these procedures are available in standard texts ([20], and see also this chapter s Further Reading).
