1 Atomic Absorption Spectrometry ( AAS )

Atomic Absorption Spectrometry (AAS) is a technique for measuring quantities of chemical elements present in environmental samples by measuring the absorbed radiation by the chemical element of interest. This is done by reading the spectra produced when the sample is excited by radiation. The atoms absorb ultraviolet or visible light and make transitions to higher energy levels. Atomic absorpti...

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...
