%X In this paper, energy-dispersive X-ray fluorescence spectromctry with thick compressed powder sample slice was used for an analogous test to measure trace elements Cu, Zn, Pb and Ba in oceanic sediments. Based on energy trace range of elements Cu, Zn, Pb and Ba, two measuring conditions were selected and the matrix of samples were determined at the same time. The ratio of background was used as internal standard. The results of measurement are satisfactory. The method is simple and readily adaptable to prompt determination for large numbers samples and multi-elements.
