Elemental analysis f moroccan marine sediments using INAA and XRF

摘要

The X ray fluorescence (XRF) analysis of marine sediments from the sediments from the Atlantic Moroccan continental shelf for the content of majork, minor and trace elements was perfrmed utilizing an energy dispersive X ray spectrometer and radioisoptope excitation with ~55Fe, ~109Cd and ~241Am annular sources. Results were assessed for accuracy by the analysis of standard reference materials Soil-7 and SL-1 Sediment from the IAEA. Some results were also compared with the analysis by instrumental neutron activation analysis (INAA) performed on the same specimens at the Laboratoire de chimie nucleaire in Strasbourg. The results for most of the elements obtained by XRF were accurate to about 10
