Abstract

The combination of wet open mineralization with a saturated Mg(NO3)2-solution and the scavening of trace elements by active carbon are discussed. Experiments with spiked aliquuots serve to establish the chemical yeilds. The procedure is then checked by the analysis of Standard (Reference) Materials from the NBS and the IAEA. The elements Sc, Fe, Co, Zn, Cu, Se, Sb, W, Hg, Au and some lanthanides can be obtained with no apparent systematic bias and at a reasonable precision.
