Determination of heavy metals (Pb, Cd, Fe and Zn) in canned sardines by acid digestion method / Azlan Shah Abdul Rahman

In this study, four heavy metals in local canned sardines were determined after acid digestion using concentrated nitric acid and concentrated hydrochloric acid. Iron, cadmium, zinc and lead in the samples were determined by atomic absorption spectroscopy. The metal contents, expressed in mg kg-1 we...
