Atomic absorption spectrometry of ytterbium using carbon tube atomizer

Interferences in the quartz tube atomizer during arsenic and antimony determination by hydride generation atomic absorption spectrometry

Interferences of some metals in the determination of arsenic by hydride generation atomic absorption spectrometry utilizing a quartz tube atomizer were studied. The atomizers were coated under vacuum with Ni, Au, Pd and Cr. The arsenic signal was almost totally suppressed by all the metal coatings and thus the interferences from metal ions in the determination of arsenic were attributed both to...

Extraction and Determination of Heavy Metals Using Silver Coated Magnetic Nanoparticles and Flame Atomic Absorption Spectrometry

A rapid, simple and sensitive magnetic solid phase extraction (MSPE) method was developed for the pre-concentration and determination of copper and cadmium ions. In this study, modified Fe3O4@Ag nanoparticles were synthesized and then ligand 2-isonicotinoyl hydrazine carbodithiolate (ITHCDT) was bonded to silver due to the formation of covalent bond of S-Ag. In this method, copper and cadmium i...

Cr (VI)/Cr (III) SPECIATION BY IN SITU ELECTRODEPOSITION ONTO TUBE PRIOR TO ELECTROTHERMAL ATOMIC ABSORPTION SPECTROMETRY

Sensitivity Enhancement for Flame Atomic Absorption Spectrometry Using an Atom Concentrator Tube, the ACT 80 Author

A simple attachment to enhance the sensitivity of flame atomic absorption spectrometry (FAAS) is described along with some performance results and practical applications. An historical review is also presented.

Determination of Rhodium(III) Ions by Flame Atomic Absorption Spectrometry after Preconcentration with Modified Magnetic Activated Carbon

A new method for analysis of trace amount of Rh(III) ions by magnetic activated carbon modified with 2,3,5,6-tetra(2-pyridyl)pyrazine (MAC/TPPZ) as the magnetic sorbent has been proposed. The proposed adsorbent was found to be advantageous over conventional solid phase extraction (SPE) in terms of operational simplicity and low time-consuming. The experimental parameters affecting the extractio...
