Mise au point d'une technique d'extraction des éléments traces métalliques dans les produits de la mer et leurs dosages par spectrophotométrie d'absorption atomique

Abstract

The aim of our study is to adopt a technique of extraction of trace metal elements in fishery products. Three extraction techniques were used to mineralize the different anatomical parts of the mussel from two coastal regions of Algeria (Skikda and El Kala). The assay was performed by atomic absorption spectrophotometer with flame and graphite furnace. Given the results, the extraction technique in the microwave seems the more accurate and more reproducible with a recovery percentage close to 100%. Also the analysis of trace metal elements in mussels did not reveal the presence of metal contamination of these products.
