GOLD IN TWENTY‐SIX JAPANESE GEOCHEMICAL REFERENCE SAMPLES

Shigeru Terashima, S. Itoh, Atsushi Ando

Open publisher page 8 citations

Abstract

Gold has been determined in 26 geochemical reference samples with graphite furnace AAS after digesting the samples with aqua regia and hydrofluoric acid and extracting gold by methyl isobutyl ketone (MIBK). This method yields clearly higher values than those by the partial attack using aqua regia digestion.
