Rapid determination of zinc in foods by flow injection analysis with flame AAS using gradient calibration method
(2004-09-01)
A calibration method was developed using flow injection analysis (FI) with a Gradient Calibration Method (GCM). The method allows the rapid determination of zinc In foods (approximately 30 min) after treatment with ...
Iron determination by FAAS in fish feed and feces after ultrasound-assisted extraction
(2009-01-01)
This paper proposes a method to determine iron in samples of fish feed and feces using ultrasound in the extraction of the analyte and in subsequent quantification by flame atomic absorption spectrometry. Using HCl 0.10 ...

Evaluation of quartz tubes as atomization cells for gold determination by thermospray flame furnace atomic absorption spectrometry
(Pergamon-Elsevier Science Ltd, 2012-11)
This work describes the development of a new analytical procedure able to determine gold by thermospray flame furnace atomic absorption spectrometry (TS-FF-AAS) using nickel tubes (NiT) and quartz tubes (QT) as atomization ...
An on-line continuous flow system for copper enrichment and determination by flame atomic absorption spectroscopy
(2000)
An on-line enrichment flow system has been developed in order to determine trace amounts of copper in seawater and biological samples. It is based on the chemical sorption of copper(II) ions onto a minicolumn packed with ...
Flame AAS determination of metal ions in fuel ethanol after preconcentration on acid carboxymethylcellulose (CMCH)
(Elsevier B.V., 1999-01-01)
This paper describes the preparation of acid carboxymethylcellulose (CMCH), and the results of a study on the adsorption and preconcentration (using batch and flow-through column methods) of Cd(II), Cu(II), Cr(III), Fe(III), ...
