Atomic absorption spectroscopy (AAS) is based upon the principle that free atoms in the ground state can absorb light of a certain wavelength. These very specific wavelengths give the technique excellent specificity and detection limits in the AAS analysis. Absorption for each element is specific, no other elements absorb this wavelength.

· Atomic absorption spectroscopy is an instrumental analytical technique for rapid trace metal analysis. It is based on element specific wavelength light absorption by state atoms within the flame or electro thermal graphite furnace. This technique was introduced for analytical purpose in 1950s by Alan Walsh and Alkemade under the designation of ...
Methods for extraction and analysis of chromium metal were developed and established. Analysis were carried out using atomic absorption spectroscopy (AAS) to estimate the contents of chromium, iron, calcium, and magnesium. Xray fluorescence (XRF) was used to evaluate the levels of chromium, iron, and calcium in the ore.
