Abstract
A procedure which permits the simultaneous determination of six major and minor elements (Al, Fe, Ca, Mg, Na, P) and eight trace elements (Be, Co, Cu, Mn, Ni, Pb, V, Zn) in near-shore marine sediments by inductively coupled plasma atomic emission spectrometry is described. Dissolution of the samples is achieved with a mixture of nitric, perchloric, and hydrofluoric acids in sealed Teflon vessels. Accurate calibration for all elements can be achieved with simple aqueous standards, provided that proper correction for various spectroscopic interferences is made. The accuracy of the method has been confirmed by analysis of two marine sediment reference materials, MESS-1 and BCSS-1, recently produced in these laboratories. The method was not suitable for determination of As, Cd, and Mo in these materials because of inadequate sensitivity nor for Cr and Ti because of incomplete dissolution.
