Determination of platinum by graphite furnace atomic absorption spectrometry in foods and beverages using an automated on-line separation-preconcentration system

Trace analysis of Pt (IV) metal ions in roadside soil and water samples by Fe3O4/graphene/polypyrrole nanocomposite as a solid-phase extraction sorbent followed by atomic absorption spectrometry

“…These methods used more sensitive detection methods (e.g., FI-ETAAS, ETAAS, ICP-AES and ICP-OES) than the detection method used in this work (FAAS). So, the proposed method is comparable with most of the published reports[22,23,27,30,[50][51][52][53][54][55][56].…”

“…Comparison between the analytical performances of the proposed method with the other preconcentration methods used for SPE of Pt (IV).other works used for Pt (IV) analysis[22,23,30,[54][55][56]. These methods used more sensitive detection methods (e.g., FI-ETAAS, ETAAS, ICP-AES and ICP-OES) than the detection method used in this work (FAAS).…”

Recent advances in the preconcentration and determination of platinum group metals in environmental and biological samples

“…The issue of platinum speciation and its impact on biological systems, toxicity and environmental behavior are very important. So far, however, there are very few works dealing with the platinum speciation [16,17]. The behavior and fate of rhodium and its compounds in the environment is almost unknown.…”

“…Another new ligand for solid phase extraction of trace metals (Cd, Cu and Ni) from leafy vegetables was investigated by Chandra et al 211 Amberlite XAD-2 was functionalised with 2-hydroxyacetophenone thiosemicarbazone (HAPTSC) which allowed 20 sorption-desorption cycles to be carried out with o1.5% variation. Similar technology was employed by Ojeda et al 212 using silica gel functionalised with 1,5-bis(di-2-pyridyl)methylene thiocarbohydrazide (DPTH-gel) for the determination of Pt in food and beverages. In this case, the column was placed in the autosampler arm.…”
