The phrase "atomic absorption procedure" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in chemistry or analytical methods involving the measurement of elements.
Example: "The atomic absorption procedure was employed to determine the concentration of lead in the water samples."
Alternatives: "atomic absorption method" or "atomic absorption technique".
Dried mushroom samples were analysed using an atomic absorption spectrophotometer following the procedures described by Jiang et al. 2011 [14].
These modern procedures include atomic absorption spectroscopy (based on the absorption of light of certain wavelengths by atoms present in a flame) and X-ray fluorescence (based on the emission of radiation of characteristic wavelengths when X rays impinge on a sample).
Vitamin E was analysed by high-performance liquid chromatography (HPLC), and selenium by atomic absorption spectroscopy, according to standard procedures at the National Veterinary Institute.
By means of an extraction procedure succeeded by atomic absorption spectrometric analysis it was shown that the Sb ions dissolved during the oxidation exist in H2SO4 in the trivalent state even at potentials well above the equilibrium potential of the Sb V /Sb III) couple.
Water arsenic analyses were performed at a Water Quality Testing Laboratory in Dhaka using flow injection-hydride generation atomic absorption spectrometry (FIHG-AAS) following the standard procedure [ 20].
Elemental platinum in plasma and ultrafiltrate was determined by flameless atomic absorption spectrometry using a modification of a procedure described by Kloft et al (1999a).
The analysis was done with an atomic absorption spectrophotometer (PerkinElmer 3100; PerkinElmer), according to the procedure reported by Crecelius et al. (1986).
Heavy metals including chromium, nickel, copper, zinc, cadmium, and lead were determined through atomic absorption spectrophotometer after tissue digestion by adopting standard procedures.
The present paper proposes a preconcentration procedure for lead determination using flame atomic absorption spectrometry (FAAS).
