A novel fiber-packed column for on-line preconcentration and speciation analysis of chromium in drinking water with flame atomic absorption spectrometry
(Elsevier Science, 2009-02)
A novel on-line preconcentration and determination system based on a fiber-packed column was developed for speciation analysis of Cr in drinking water samples prior to its determination by flame atomic absorption spectrometry ...
Leadcare II Comparison with Graphite Furnace Atomic Absorption Spectrophotometry for Blood Lead Measurement in Peruvian Highlands
(SpringerIND, 2022-05-30)
"Peru is one of the countries with the highest lead
contamination in the world. Biological monitoring has limitations due to the shortage of laboratories with validated
methodologies for the measurement of blood lead, ...
Investigation of spectral interference in the determination of Pb in road dust using high-resolution continuum source graphite furnace atomic absorption spectrometry and direct solid sample analysis
(Royal Society of Chemistry, 2018-04)
Direct solid sample analysis using graphite furnace atomic absorption spectrometry (GF AAS) is an attractive alternative because no sample pretreatment is necessary. However, the major obstacles of this technique are ...
A metallic furnace atomizer in hydride generation atomic absorption spectrometry: Determination of bismuth and selenium
(Pergamon-Elsevier Science Ltd, 2008-08)
A flow injection hydride generation system with a metal furnace atomizer (Inconel 600® alloy) was employed for Bi and Se determination. The presented methods have linear ranges up to 200 and 500 μg L- 1 for Bi and Se, ...

Selective determination of Cr (VI) by on-line solid phase extraction FI-SPE-FAAS using an ion exchanger resin as sorbent: An improvement treatment of the analytical signal
(Elsevier Science, 2017-01)
A flow injection (FI) technique based on an on-line solid phase extraction (SPE) coupled with flame atomic absorption spectroscopy (FAAS) to selectively quantify chromium (VI) in the presence of chromium (III) was developed. ...
l-Tyrosine immobilized on multiwalled carbon nanotubes: A new substrate for thallium separation and speciation using stabilized temperature platform furnace-electrothermal atomic absorption spectrometry
(Elsevier Science, 2009-12)
An approach for the separation and determination of inorganic thallium species is described. A new sorbent, l-tyrosine-carbon nanotubes (l-tyr-CNTs), was used and applied to the analysis of tap water samples. At pH 5.0, ...
Non-chromatographic determination of ultratraces of V(V) and V(IV) based on a double column solid phase extraction flow injection system coupled to electrothermal atomic absorption spectrometry
(Elsevier Science, 2009-08)
In this work, a non-chromatographic procedure for the on-line determination of ultratraces of V(V) and V(IV) is presented. The method involves a solid phase extraction-flow injection system coupled to electrothermal atomic ...
Two-step separation and determination of inorganic As species in water, soil and sediment samples by implementing two ionic liquids in dispersive liquid–liquid microextraction with electrothermal atomic absorption spectrometry detection
(Elsevier Science, 2020-12)
A highly efficient liquid-liquid microextraction method based on two magnetic ionic liquids (MILs) as extraction solvents for the determination of inorganic As species in water, soil and sediment samples, with electrothermal ...
