Determination of Molybdenum in Fifty Three Geochemical Reference Materials by Flameless Atomic Absorption Spectrometry

Abstract

The molybdenum (Mo) contents of fifty three geochemical reference materials issued by ANRT, GIT‐IWG, NIST and GSJ, have been determined by atomic absorption spectrometry, using a graphite furnace atomiser, after extraction of Mo dithiol with isoamyl acetate. Detection limits for this method (0.01 μg g−1) are ten times smaller than for most classical methods. The agreement between the present results and published data is satisfactory.
