摘要：
An anion exchange procedure has been optimized for the analysis of platinum group elements (PGEs) in geological samples at low abundances by adding two stages: chlorination and replicate sorption onto a small anion exchange column. Combined with neutron activation analysis (NAA) and ultrasonic nebulization inductively coupled plasma mass spectrometry (USN-ICP-MS) determination, this procedure is evaluated by replicate analyses of PGEs (Ru, Pd, Os, Ir, Pt), Au, Ag and Re in two reference materials, WMG-1 and WITS-1. The suitability of the method for actual geological samples was demonstrated by analyzing target rocks and breccias from the Bosumtwi impact crater, Ghana. (C) 2001 Elsevier Science B.V.
