摘要
A method for the determination of environmentally significant elements in estuarine sediments is presented. Samples were digested with a mixture of nitric, perchloric and hydrofluoric acids in closed PTFE vessels without metallic mantle. Cadmium, chromium, copper, manganese, nickel, lead and zinc were determined by atomic absorption spectrometry. Good recoveries were obtained by analyzing those elements in reference sediments. Samples of estuarine sediments from Odiel river (southwest of Spain) were analyzed.
