Method validation for arsenic speciation in contaminated soil by HPLC-ICP-MS coupling method

Atomic spectrometry update – a review of advances in environmental analysis

“…Although the coupling of chromatographic separation with ICP-MS is now routine, procedures continue to be developed, optimised and validated. Examples included: an HPLC-ICP-MS method 136 for As speciation in soil extracts prepared by MAE in 0.5 M phosphoric acid; an HPLC-ICP-MS method 137 for As speciation in foods of plant origin that was applied to cereals, seaweed and vegetables; and an HPLC-ICP-MS method 138 for Sb speciation in soils, which was used to compare the impacts in southern Poland of a slag heap from a historical Pb/Zn mine, a modern WEEE plant and a motorway. Of particular interest to the wine enthusiasts amongst the ASU readership was an IC-ICP-MS method based on detection of the PO + ion that could detect 139 residues of phosphonic acid, a substance banned from use in organic viticulture in the EU since 2013.…”

Removal of Inorganic Pollutants from Wastewater: Innovative Technologies and Toxicity Assessment

“…It was observed that arsenic was a major fraction of particulate matter, with 78.7 to 78.9% in different matters studied. A study reported the use of HPLC-ICP-MS technology for the determination of arsenic in contaminated soil [72]. The study reported different limits of quantification for different arsenic species.…”

Validación de un método analítico para la determinación de arsénico total en muestras de suelo por espectrofotometría de absorción atómica con generación de hidruros

“…Cuando el límite máximo permisible (LMP) es ≥ 0,1 ppm, el criterio de aceptación para el LOD es ≤ 1/10 LMP y para el LOQ, ≤ 1/5 LMP (Duffau et al, 2010). Cabe mencionar que el LMP considerado fue 20 mg•kg -1 , establecido por la FAO (El Himri et al, 2022).…”

“…Los resultados obtenidos fueron expresados mg•kg -1 y se compararon con el valor de referencia (El Himri et al, 2022).…”

“…El arsénico (As) es un elemento de gran distribución en la corteza terrestre; se encuentra naturalmente en el suelo y otros compartimentos ambientales como producto de la erosión de las rocas, la precipitación y la actividad volcánica (Reid et al, 2020;El Himri et al, 2022).…”
