Validation of Atomic Absorption Spectroscopy (AAS) for Trace Elements Analysis of Environmental Samples

Abstract

The investigation focused on the validation of the methodology used in determining the presence of specific trace elements in environmental soil concern. Atomic Absorption Spectroscopy (AAS) available in Gombe State University, Nigeria was employed in analyzing the elemental concentrations on the certified values in three reference materials obtained from the International Atomic Energy Agency (IAEA) and National Institute of Standards & Technology (NIST). The elements determined were Cd, Co, Cr, Cu, Mg, Mn, Ni, and Pb. The percentage recovery of the measured trace elements concentrations were found within the range of 90–100% of the certified values for most of the elements; the machine was calibrated using standard solution.
