Selective determination of Sb(III) by gas chromatography-quartz furnace atomic absorption spectrometry after derivatization with triphenylmagnesium bromide

Determination of antimony in soils and vegetables by hydride generation atomic fluorescence spectrometry and electrothermal atomic absorption spectrometry. Optimization and comparison of both analytical techniques

“…1 In comparison to arsenic, little information is available on the environmental chemistry of antimony. 2 Nevertheless, antimony is a cumulative toxic element that has chemical and toxicological properties similar to those of arsenic. 3 Indeed, As(III) is known as a carcinogen and Sb(III) oxide has been shown to cause lung cancer.…”

Chemical vapor generation from an ionic liquid using a solid reductant: determination of Hg, As and Sb by atomic fluorescence spectrometry

“…[24][25][26] For extraction of mercury, methylmercury, arsenic and antimony into RTIL by LLE, 300 mL [C 4 mim]PF 6 and appropriate amounts of complexing agents (APDC or dithiozone) were added into a polyethylene tube containing 10 mL working standard or sample solution. [24][25][26] For extraction of mercury, methylmercury, arsenic and antimony into RTIL by LLE, 300 mL [C 4 mim]PF 6 and appropriate amounts of complexing agents (APDC or dithiozone) were added into a polyethylene tube containing 10 mL working standard or sample solution.…”

“…18 RTILs retain many unique properties, such as negligible vapor pressure, properties of Lewis acid, good thermal stability, tunable viscosity, miscibility with water and organic solvents, and good extractability for various organic compounds and metal ions. [22][23][24] Commonly, dilution of the organic extractant containing the analyte with a mixture of inorganic acid (HCl and/or HNO 3 ) solution and antifoam reagents or back-extraction of the analyte to an aqueous phase is required prior to CVG. [19][20][21] Apart from the Grignard alkylation for the derivatization of organo-tin, alkyl-lead and antimony species, direct CVG of volatile species of an analyte from the organic extraction phase with sufficient yield has rarely been realized.…”

Preliminary results of a quick, simple method of detecting antimony in water samples

“…Capillary electrophoresis (CE) with indirect UV detection was used by Casiot et al [8] to determine levels of arsenic, selenium, antimony and tellurium species in water samples. Chromatographic techniques, such as gas chromatography (GC) with detection by quartz furnace atomic absorption spectrometry (GC-QFAAS) [9] or high performance liquid chromatography coupled with inductively coupled plasma mass spectrometry (HPLC-ICP-MS) [10], have also been used. Moreover, ICP-MS was the technique established by the EPA for the determination of contaminants (such as antimony) in drinking water [11].…”
