Using Atomic Absorption Spectrometry (AAS) for the Determination of Aluminum and Zinc in Wrapped Chocolate and Chips samples

Abstract

This study was carried out to determine the contents of Aluminum and Zinc in wrapped Chocolate and Chips sample by atomic absorption instrument. Ten different samples of Chocolate collected from local markets in some Libyan cities. The concentrations of Aluminum in the selected samples in this study fluctuated in the range of 1.658 and 5.433 ppm. Whereas the concentrations of zinc ranged between 3.540 and 7.723 ppm. The higher concentration of Aluminum was recorded in sample No 10, whereas the lower concentration of Al was recorded in sample No 1. On the other side, the low contents of Zinc were recorded in sample 1. The results of this study recorded that most of the selected samples containing high values of Aluminum and Zinc than reported by the World Health Organization (WHO).
