Introduction • Atomic absorption spectroscopy is quantitative method of analysis of metals and some non-metals • The technique was introduced in 1955 by Sir Alan Walsh in Australia • Concentrations are found in g/mL range (ppm and ppb) For mercury analysis, no heating is required because the chemicals form elemental mercury, which passes as a vapor into the atomization cell. chem.-3rd sem.

The atoms absorb ultr aviolet or visible light and make transitions to higher energy levels. Atomic absorption spectroscopy (AAS), in both flame and electrothermal modes, is one of the best methods for determination of the metal concentrations in various specimens that dissolved in acid (Kalbasi and Mosaddegh, 2012). Measured signal and analytical concentration 1. Atomic absorption spectroscopy instruments place a sample in a high temperature flame that yields atomic species and passes selected, element specific, illumination through the flame to detect what wavelengths of light the sample atoms absorb. This is done by reading the spectra produced when the sample is excited by radiation. Atomic absorption spectrometry (AAS) is a very sensitive method of elemental analysis, allowing the determination of metals in a variety of samples at the picogram level. Consequently light is absorbed by a ground state atom or emittedby an excited atom at very precise wavelengths, resulting in line spectra. In the UV-VIS domain, each element has hundreds to thousands of absorption/emission lines.
