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...
متن کاملFraunhofer effect atomic absorption spectrometry.
The dark lines in the solar spectrum were discovered by Wollaston and cataloged by Fraunhofer in the early days of the 19th century. Some years later, Kirchhoff explained the appearance of the dark lines: the sun was acting as a continuum light source and metals in the ground state in its atmosphere were absorbing characteristic narrow regions of the spectrum. This discovery eventually spawned ...

متن کاملAn Analytical Method Validation for Atomic Absorption Spectrometry Analisys of Total Zinc from Insulin
abstract: An analytical method validation represents a complete investigation of the materials’ properties, following certain steps, being necessary for “proving the fit for purpose of an analytical method”. The validation procedure demonstrate that a defined validation protocol for an analytical method applied to a specified testing material and a defined concentration of the analyt – named an...
متن کاملGRAPHITE FURNACE ATOMIC ABSORPTION SPECTROMETRY WITH MAlIlRIX MODIFICATION FOR DETERMINATION OF LEAD IN DRINKING WATER
An amoniumvanadate plus sodium molybdate mixed modifier Graphite Furnace Atomic Absorption Spectrometric method has been developed for determination of traces of lead in drinking water. The concentration of lead in the sample is obtained by direct comparison to linear working graph prepared from aqueous standards in the modifier medium, The results indicate the better performance of the pro...
