Determination of some trace metals in water and sediment samples by flame atomic absorption spectrometry
after coprecipitation with cerium(IV) hydroxide.
Several analytical (atomic absorption spectrometry
) as well as spectroscopic (UV-Vis spectrophotometry, EPR) methods have been applied to study the mechanism of the oxidation process of Mn(II) by an unknown factor produced during the microbial growth.
Spectrometer features: The Pulsar Metal Alloy Analyzer is a spectrometer that combines the solid-sampling capability of glow discharge with the specificity of atomic absorption spectrometry
. It provides:
Although Inductively Couple Plasma spectrometry (ICP) has challenged atomic absorption spectrometry
as the premier elemental analysis technique, AA has remained the most popular technique for basic analysis.
Serum and urine variables were determined during the last two weeks of each 90-day dietary period by standard methods using commercially available kits, ion specific electrodes or atomic absorption spectrometry
. A p value less than 0.10 was considered significant.
The initial and final concentrations of the metal ions were determined by atomic absorption spectrometry
. After each experiment, the copper ion retained in the column, was removed by using a solution with a 10% of nitric acid and the liberated copper was determined by absorption spectrometry
If the atomic absorption spectrometry
equipment fails, for example, the test tubes containing the samples are placed in a separate rack for manual testing."
The extracts are analysed for the micro-nutrients using the analytical method described in EN16963 - Fertilizers - Determination of boron, cobalt, copper, iron, manganese, molybdenum and zinc using ICP-AES or EN 16965 - Fertilizers - Determination of cobalt, copper, iron, manganese and zinc using flame atomic absorption spectrometry
Electrothermal vaporization-inductively coupled plasma-atomic emission spectrometry (ETV-ICP-AES), electrothermal vaporization-inductively coupled plasma-mass spectrometry (ETV-ICP-MS), electrothermal vaporization-inductively coupled plasma-optical emission spectrometry (ETV-ICP-OES) and electrothermal atomic absorption spectrometry
(ETAAS) are widely used for the direct analysis of aluminum oxide powders.
