Atomic absorption spectrophotometry for the analysis of metalcontents in tobacco samples

摘要

Spectroscopy is one of the most important tools for studying the structures of atoms and molecules. Paper underlines the procedures required for the determination of metal contents in tobacco samples. Sampling procedures, sample preparation, and atomic absorption instrumentation requirements are presented. Particular attention is given to the determination of metals as Pb, Cr, Li, Cu, Au, Co using atomic absorption spectroscopy. A dual-beam Atomic Absorption Spectrophotometer was used for the measurements. The concentration of these metals in five different tobacco samples is given.
