Atomic absorption spectrometry and other instrumental methods for quantitative measurements of arsenic

Progress in instrumental methods for quantification of arsenic during the past decade is reviewed. Particular emphasis is placed on atomic absorption spectrometry, where major progress has been made in flame methods in conjunction with hydride generation procedures and in electrothermal methods with the graphite furnace. Specific materials in which arsenic is quantified by atomic absorption techniques are also listed. Progress in the application of neutron activation—γ-spectrometry, emission spectrometry, electrometric methods, x-ray procedures and atomic fluorescence spectrometry is also reviewed. The limits of detection and time requirements of all the techniques are compared.
