“…the faradic current connected with the electrode reaction during stripping. Traces of chromium were also determined by means of AdSV after binding Cr(III) ions, stable or instantaneous, with the selected ligands forming complexes such as dimethyldioxime (DMG) [84], diphenylcarbazide [85,86], pyrocatechol violet [87,88], 4-(2-pyridilazo)-resorcinol (PAR) [89] and DTPA [90], which are then adsorbed on the surface of the indicative electrode.…”

This article reviews the voltammetric methods of chromium determination, including adsorptive and catalytic adsorptive stripping voltammetry at liquid mercury, metallic films, and modified carbon paste electrodes. The principle applications of the catalytic adsorptive stripping voltammetric method of chromium(VI) determination in the presence of DTPA and nitrate, most useful in the analysis of chromium traces and its speciation, is presented in detail. Special emphasis is put on the presentation and characterization of the voltammetric procedures which make it possible to conduction speciation studies of chromium(VI) in the presence of a great excess of chromium(III) and surfactants. This survey is based on 173 articles.

Voltammetric Determination of Cr(VI) in Cr(VI)- and [Cr(VI)+Mn(IV)]-Spiked Reference Soil Samples as a Function of Incubation Time and Extraction Procedures

In-house reference soils were spiked with Cr(VI) or with Cr(VI) plus Mn(IV), incubated at constant humidity and temperature for different periods of time, extracted with distilled water, neutral phosphate buffer or carbonate/hydroxide solutions and tested for Cr(VI) by an adsorptive cathodic stripping voltammetric method. The extraction by carbonate/hydroxide was not satisfactory, likely because of electrode poisoning by some organic compounds. The results showed that extractions by water or neutral phosphate buffer are fully compatible with the AdCSV analysis of Cr(VI). The proposed procedure can be used to detect Cr(VI) in soil extracts down to mg/kg level.
