Sampling preparation and appropriate choice of analytical method are two important points to consider in obtaining reliable data on toxic metal analysis in marine environment. This work aims to know the quality of two or three acid combinations in metal extraction of Cd and Cu in marine sediment as preliminary steps in sampling preparation. The result was tested through its effectiveness and accuracy by looking at its quantitative aspect and relative standard deviation. Determination of Cd and Cu was carried out by Attomic Absorption Spectroscopy and the result has shown that combination of HCl/HNO3/HClO4 is having best effectiveness and accuracy. The amount of extract obtained are 13.16 ug/g for Cd and 74.93 for Cu. Deviation standards for Cd and Cu are 1.23% and 0.58% respectively.   Key words : extraction, marine sediment, toxic metal, effectiveness, accuracy, deviation standard
