Atomic Absorption and Emission Spectrometry, Solution‐Based in Iron and Steel Analysis

Abstract

The use of solution‐based atomic absorption spectrometry (AAS) and atomic emission spectrometry (AES) in iron and steel analysis is presented. The article is arranged in different sections dealing with the history relevant to the introduction and the acceptance of these techniques in iron and steel laboratories and their application to iron and steel analysis. A special emphasis is given to the application studies described in the literature for determining the almost forty elements which can be present in steels. Topics such as sampling and sample preparation, spectrometric measurement, interferences, calibration, and quality assurance criteria are discussed. Finally a brief overview of the standard methods of analysis is presented.
