Abstract

            Heavy metals like Fe and Mn at low concentrations are essential metals for enzymatic activities and many biological processes. Two wet digestion methods have been applied for the determination of Iron (Fe) and Manganese (Mn) in various edible parts of some fresh vegetables and fruits. The samples were analyzed by Flame Atomic Absorption Spectrometer (AAS) and Atomic Emission Inductive Coupled Plasma spectroscopy (ICP-AES). The results obtained in this study showed that the second digestion method is more reliable for (Fe). The procedure yields precision varied between 0.4% for Mn and 1.2% for Fe.
