A comparative evaluation of different ionic liquids for arsenic species separation and determination in wine varietals by liquid chromatography – hydride generation atomic fluorescence spectrometry
(Elsevier Science, 2016-09)
The application of different ionic liquids (ILs) as modifiers for chromatographic separation and determination of arsenite [As(III)], arsenate [As(V)], dimethylarsonic acid (DMA) and monomethylarsonic acid (MMA) species ...
Activated carbon-modified knotted reactor coupled to electrothermal atomic absorption spectrometry for sensitive determination of arsenic species in medicinal herbs and tea infusions
(Elsevier, 2015-01)
A flow injection system based on a modified polytetrafluoroethylene (PTFE) knotted reactor (KR) was developed for arsenite [As(III)] and arsenate [As(V)] species preconcentration and determination by electrothermal atomic ...

Sequential injection analysis implementing multiple standard additions for As speciation by liquid chromatography and atomic fluorescence spectrometry (SIA-HPLC-AFS)
(ELSEVIER SCIENCE BV, 2011)
An analytical procedure for multiple standard additions of arsenic species using sequential injection analysis (SIA) is proposed for their quantification in seafood extracts. SIA presented flexibility for generating multiple ...
Inorganic As speciation and bioavailability in estuarine sediments of Todos os Santos Bay, BA, Brazil
(2010)
The spatial distribution of As (total As, As (III) and As (V)) in estuarine sediments from the main tributar-
ies of Todos os Santos Bay, BA, Brazil, was evaluated under high and low flow conditions. The concentra-
tions ...
Determination of inorganic arsenic in Argentinean rice by selective HGAAS: Analytical performance for paddy, brown and polished rice
(Academic Press Inc Elsevier Science, 2020-08)
Inorganic As (iAs) species require strict monitoring in foodstuff due to their toxicity. Rice is of particular concern, with recent legislations establishing limits for these species. In this work we develop a method based ...
