The certification of the contents (mass fractions) of Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Nd, Pr, Sc, Sm, Tb, Tm, Y, Yb, Th and U in Estuarine sediment

Funded under: FP5-GROWTH

Abstract

This report describes the preparation of an estuarine sediment reference material, CRM 667, the homogeneity and stability studies and the analytical work performed for the certification of the contents of rare earth elements and two additional elements. The report contains all the results and gives the methods used to certify the contents of 15 rare earth elements (REE) Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Nd, Pr, Sc, Sm, Tb, Tm and Yb and of the elements Th and U (mass fractions expressed as mg.kg{-1} on a dry matter basis). Indicative values are given for the content of the REE Y and for 14 trace elements: Cd, Br, Co, Cr, Cs, Cu, Fe, Mn, Ni, Pb, Sb, Se, Ta and Zn.
