“…The reduction of Sb(V) to Sb(III) was shown to increase with L-cysteine concentration (Feng et al 1999). Considering the low concentrations in drinking water in contact with plastic, the concentration of L-cysteine must allow quantitative reaction with Sb(V).…”

A novel, simple, sensitive, and efficient method for the speciation of inorganic antimony by dispersive liquid-liquid microextraction (DLLME) combined with graphite furnace atomic absorption spectrometry (GF-AAS) is reported. The method uses a hydrophobic complex of antimony(III) with a new chelating agent, 1,2,6-hexanetriol trithioglycolate, at neutral pH. The complex was extracted into the organic phase, whereas antimony(V) remained in aqueous solution. The concentration of antimony(V) was obtained by subtracting the antimony(III) concentration from the total antimony concentration following the reduction of antimony(V) to antimony(III) by L-cysteine. The pH, extraction and dispersive solvents and volumes, and concentration of 1,2,6 -hexanetriol trithioglycolate were optimized. Under the optimized conditions, the analytical curve was linear from 0.26 to 3.2 micrograms per liter with a limit of detection of 27.0 nanograms per liter for antimony(III). The relative standard deviation was 6.8 percent at 0.52 microgram per liter antimony(III) with an enrichment factor of twenty-six. The method was employed for the speciation of antimony in leaching solution in contact with plastic; and the recoveries in fortified samples were between 94.2 and 118.0 percent.

“…Antimony exists in natural systems in the inorganic form primarily as Sb(III) and Sb(V), is naturally associated with various inorganic and organic compounds or colloids (Feng et al 1999;Deng, Chen, and Belzile 2001;Zheng et al 2006), and is present in environmental, biological, and geochemical matrices (Deng, Chen, and Belzile 2001;Zheng et al 2006). …”

“…Spectrometric techniques have been used for the speciation of Sb (Feng et al 1999;Menegario et al 2006;Zheng et al 2006;Flores et al 2007;Menegario et al 2008 Ferreira et al 2011) using hydride generation (HG) systems with adequate sensitivity. Sb(V) was determined indirectly from the difference between the total concentration and the concentration of Sb(III).…”

Speciation of Sb(III) and Sb(V) was investigated using hydride generation with the selective formation of stibine from Sb(III). A continuous flow system using a homemade gas-liquid separator with inductively coupled plasma optical emission spectrometry was employed.The conditions and concentrations of NaBH4, HCl, citric acid, and KI were optimized to obtain limits of detection of 0.05 for Sb(III) and 0.11 µg L 1 for total Sb without Downloaded by [Emory University] at 05:46 04 August 2015 2preconcentration. An attractive sampling rate of 26 analyses h 1 was obtained, suggesting application for routine analysis. The method was employed for the determination of Sb (III) and total Sb in bottled drinking water, and recovery values between 82.0 and 98.8% with relative standard deviation lower than 6.2% were observed, demonstrating appropriate accuracy and precision.

“…Thus, in order to obtain correct information on toxicity and biotransformation of antimony, it is necessary not only to determine the total antimony in the different environmental and biological samples, but also to determine antimony in its different oxidation states. Different approaches have been reported for the speciation analysis of Sb being the combination of a powerful separation technique in environmental and biological samples such as electrothermal vaporization inductively coupled plasma atomic emission spectrometry (ETV-ICP-AES) [4], hydride generation (HG) and inductively coupled plasma optical emission spectrometry (HG-ICP OES) [5], hydride generation inductively coupled plasma atomic emission spectrometry (HG-ICP-AES) [6], electrothermal atomic-absorption spectrometry (ET-AAS) [7], atomic fluorescence spectroscopy (AFS) [8] kinetic-spectrophotometric determination [9], electrochemical [10], and hydride generation atomic fluorescence spectrometry (HG-AFS) [11].…”
