Terminology3.1 For definitions of terms not listed here, see TerminologyE1605.3.2 anodic stripping voltammetryan electroanalyticaltechnique in which the concentration of analyte metal speciesdissolv
16、ed in solution is determined in the following manner:The analyte is first deposited (preconcentrated) electrochemi-cally by reducing the dissolved ion in solution to immobilizedmetal species at an electrode surface (such as mercury orbismuth). The metal is deposited at an applied potential(voltage)
17、which is negative of the standard oxidation potentialfor the metal/ion redox couple. After deposition, the precon-centrated metal species is then stripped from the electrode byapplying a positive potential sweep, which causes anodicoxidation of the analyte metal species to dissolved ion. Thecurrent
18、associated with this reoxidation is measured. The peakcurrent is proportional to the original concentration of dis-solved analyte species over a wide range of concentrations.3.3 colorimetryan analytical technique that is similar tospectrophotometry (see 3.5), except that ultraviolet-visiblelight of
19、a single, narrow wavelength range is passed through asample cell containing dissolved analyte, and the absorptionmeasured.3.4 reflectancea measurement technique (subset of spec-trophotometry; see 3.5) in which light is reflected off of areflecting surface and measured by a detector. The amount ofref
20、lected light may be a function of analyte concentration.3.5 spectrophotometryan analytical technique in which aspectrum of analyte species is obtained and used to determinethe analyte concentration in the following manner. Light isdirected onto or through analyte species, and the absorption ofthis l
21、ight across a range of wavelengths is measured by adetector. The amount of absorbed light is a function of theconcentration of analyte species.4.
