Journal ArticleDOI
Determination of arsenic in agricultural soil samples using High-resolution continuum source graphite furnace atomic absorption spectrometry and direct solid sample analysis
Mauana Schneider,Heloisa R. Cadorim,Bernhard Welz,Bernhard Welz,Eduardo Carasek,Joerg Feldmann +5 more
TL;DR: A method has been developed using high-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GFAAS) for direct determination of arsenic in solid soil samples and the modifier that showed the best results was the Zr, used as a permanent modifier.
Journal ArticleDOI
Determination of sulfur in crude oil using high-resolution continuum source molecular absorption spectrometry of the SnS molecule in a graphite furnace
Heloisa R. Cadorim,Éderson R. Pereira,Eduardo Carasek,Bernhard Welz,Bernhard Welz,Jailson B. de Andrade +5 more
TL;DR: An analytical method for the determination of sulfur, as the tin mono-sulfide (SnS) molecule, in crude oil using high-resolution continuum source graphite furnace molecular absorption spectrometry (HR-CS GF MAS) has been developed and accuracy and precision have been evaluated.
Journal ArticleDOI
Determination of chlorine in coal via the SrCl molecule using high-resolution graphite furnace molecular absorption spectrometry and direct solid sample analysis
Éderson R. Pereira,Lucas M. Rocha,Heloisa R. Cadorim,Vanessa Dutra Silva,Bernhard Welz,Bernhard Welz,Eduardo Carasek,Jailson B. de Andrade +7 more
TL;DR: In this article, the determination of chlorine in coal is described via molecular absorption of the strontium mono-chloride (SrCl) molecule at 635.862 nm using high-resolution continuum source graphite furnace molecular absorption spectrometry (HR-CS GF MAS) and direct solid sample analysis.
Journal ArticleDOI
Effective and High-Throughput Analytical Methodology for the Determination of Lead and Cadmium in Water Samples by Disposable Pipette Extraction Coupled with High-Resolution Continuum Source Graphite Furnace Atomic Absorption Spectrometry (HR-CS GF AAS)
Heloisa R. Cadorim,Mauana Schneider,Júlia S. Hinz,Fabiana Luvizon,Adriana Neves Dias,Eduardo Carasek,Bernhard Welz,Bernhard Welz +7 more
TL;DR: In this paper, a new procedure for the preconcentration of trace amounts of free Pb and Cd by disposable pipette extraction (DPX) is proposed and Recycled cork is used as a biosorbent.
Journal ArticleDOI
Determination of fluorine in copper concentrate via high-resolution graphite furnace molecular absorption spectrometry and direct solid sample analysis – Comparison of three target molecules
Heloisa R. Cadorim,Jefferson Santos de Gois,Aline R. Borges,Maria Goreti R. Vale,Maria Goreti R. Vale,Bernhard Welz,Bernhard Welz,Heike Gleisner,Christina Ott +8 more
TL;DR: The goal of the present work is the development of a method for the determination of fluorine in copper concentrate using high-resolution graphite furnace molecular absorption spectrometry and direct solid sample analysis.
