description

Nach einem Druckaufschlus bei 170°C von 5 g Gesteinsprobe mit HF und aqua regia werden die Edelmetalle Au, Pd, Pt, Rh und Ir durch selektive Adsorption auf den Ionenaustauscher SARAFION NMRR von der restlichen Matrix abgetrennt. Im Thioharnstoffeluat konnen die Edelmetalle mit der elektrothermalen AtomabsorptionsSpektrometrie quantitativ bestimmt werden. Die Methode wurde durch Analyse von internationalen Gesteinsstandards und Meteoriten gepruft.
