Notes:
Abstract Noble metals are preconcentrated and separated from the matrix elements by adsorption on proper complexing ligands immobilized on silica gel and subsequent elution. Preconcentration factors of 5–10 were achieved. The reliability of the method was proved by analysis of a spiked soil material and a CRM with ICP-AES and ICP-MS. Ag, Au, Pd and Pt showed a good recovery in the spiked material. The indicative value for gold in the CRM (145 BCR) could be confirmed.
