Application of Internal Standard Method for Several 3d-Transition Metallic Elements in Flame Atomic Absorption Spectrometry Using a Multi-wavelength High-resolution Spectrometer

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...

Preconcentration of Cu(II)with magnetic nanocomposite sorbentsprior to determination by Flame Atomic Absorption Spectrometer

A simple, highly sensitive, accurate and selective method for determination of trace amounts of Cu2+ in water samples .In this paper, Chitosan was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-CHITOSAN sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a novel nano-Fe3O4-Chitosan-ED.Flame atomic abs...

Determination of Copper at Wide Range Concentrations Using Instrumental Features of High-resolution Continuum Source Flame Atomic Absorption Spectrometry

This work describes a method to determine Cu at wide range concentrations in a single run without need of further dilutions employing high-resolution continuum source flame atomic absorption spectrometry. Different atomic lines for Cu at 324.754 nm, 327.396 nm, 222.570 nm, 249.215 nm and 224.426 nm were evaluated and main figures of merit established. Absorbance measurements at 324.754 nm, 249....
