To determine the concentration of two heavy metals i.e; Chromium and Lead both in field grown and in vitro grown plant tissues of Tropaeolummajus after their shifting to the Kasur tanneries contaminated fields for 60 days Atomic Absorption Spectroscopy
technique was used.
The class decided to monitor this successful deposition of iron by analyzing the stream iron concentration and extractions of iron oxide deposits from the surface of rocks by atomic absorption spectroscopy
(AAS; Lee et al.
Among the investigated cations, [Na.sup.+], [K.sup.+], [Fe.sup.2+], and [Zn.sup.2+], did not show any interference in mercury analysis by cold vapour atomic absorption spectroscopy
, while [Cr.sup.3+], [Co.sup.2+], [Ni.sup.2+], and [Cu.sup.2+] significantly reduced the mercury signal, forming characteristic patterns.
A quantitative determination of zinc was carried out on a relatively uncontaminated portion of the sample, using atomic absorption spectroscopy
and the standard addition method.
3:40 THE USE OF FLAME ATOMIC ABSORPTION SPECTROSCOPY
(FAAS) TO DETERMINE THE AMOUNT OF MANGANESE PRESENT IN OXALATE OXIDASE FROM CERIPORIOPSIS SUBVERMISPORA **, Christopher Brooks * and Ellen W.
Here individual researchers cover the earliest period, looking at stratigraphy, architecture, and pottery; typo-chronological conclusions about the pottery; chipped stone assemblage; the atomic absorption spectroscopy
of copper-based objects; climate, fauna, and flora; and radiocarbon datings.
In the following article, John Drew sets out the events that led him to produce the teaching notes 'Atomic Absorption Spectroscopy
Total serum magnesium was measured with atomic absorption spectroscopy
and a Kodak Ektachem DT-60.
The oxidation of thiamine to thiochrome was quantitatively measured by using fluorescence spectroscopy and atomic absorption spectroscopy
This paper provided evidence that portable XRF analyzers could be used in the field to obtain results comparable to those obtained with flame atomic absorption spectroscopy
Lead can be tested using handheld XRF, atomic absorption spectroscopy
, inductively coupled plasma mass spectrometry or inductively coupled plasma-optical emission spectroscopy.
For more accurate quantitative measurement, the researchers adopted a second procedure: They separated the lime from the aggregate by acid extraction, and they determined the calcium level by atomic absorption spectroscopy
or ion exchange chromatography, and used this data to calculate the lime content.
