A procedure for correcting the grain size effect in heavy metal analyses of estuarine and coastal sediments 论文

摘要

Summary A series of potential reference elements (Cs, Eu, Fe, Rb, Sc, Sm and Th) was studied by Instrumental Neutron Activation Analysis (INAA) in sediment samples from the Ems Estuary in order to find a trace element that would be particularly well‐suited for employment in the Relative Atomic Variation (RAV)1 method for correcting grain size effects. It is shown that the correction procedure using the element cesium provides the most reliable results.
