“…There have been fewer reports of studies on Sb speciation in food during this review period. The determination of trace iSb in PET bottled soy sauce has been measured by IC-ICP-MS. 34 The sample was first filtered through a weak cation exchange SPE column and then subsequently washed with 3.0 mL of 0.02% l -ascorbic acid and 3.0 mL of methanol. Finally, the SPE column was eluted with 1.0 mL of 0.1% NaOH + 2% H 2 O 2 .…”

“…Among the spectrometric detection techniques, ICP-MS is indubitably the most sensitive technique for determining metals and metalloids. However, despite this great advantage, its application to speciation analysis requires a separation step of the different species before detection using ICP-MS [12][13][14][15][16][17][18][19].…”

“…A method using HPLC-ICP-MS was established for the separation and quantification of arsenic [As(III), As(V)] and antimony [Sb(III), Sb(V), SbMe 3 ] species in water and bottom sediments [15]. The combination of ion chromatography and ICP-MS allowed the determination of trace inorganic antimony in PET-bottled soy sauce [17]. An analytical strategy for antimony speciation in extracts of size-classified volcanic ash was developed by HPLC-ICP-MS [21].…”

A very simple, fast and non-chromatographic methodology for inorganic antimony speciation based on Multisyringe Flow Injection Analysis (MSFIA) employing online hydride generation (HG) ICP-MS was developed. The fully automated analysis is performed in two steps: firstly, Sb(III) is quantified by ICP-MS after chemical vapor generation; then, total antimony is determined in the presence of potassium iodide as a pre-reducer of Sb(V) to Sb(III). The Sb(V) concentration is quantified by the difference between the total antimony and Sb(III) concentrations, reaching an analysis frequency of 30 h−1. The optimization was performed using a Box Behnken design. The MSFIA-HG-ICP-MS system allows the antimony speciation analysis with a detection limit of 0.016 µg L−1 for Sb(III), working in a linear range of 0.053 to 5.0 µg L−1. This method was applied for the determination of Sb(III) and Sb(V) in water samples from Maiorca Island, Spain, and the concentrations found varied from 0.10 to 0.14 µg L−1 for Sb(III) and from 0.12 to 0.28 µg L−1 for Sb(V). The results were validated by addition/recovery tests, obtaining recoveries between 90 and 111% in both cases. Furthermore, a good precision was achieved, 1.4% RSD, and sample and reagent consumption were reduced to a few mL, with the consequent decrease in waste generation. Thus, the proposed method is a good tool for the speciation of inorganic antimony at ultra-trace levels in waters, allowing its risk assessment.
