Abstract: The behaviour for extracting Wand Mo from HC1 solution with TOPOin xylene was studied. Based on this, an extraction chromatographic method is proposed for separation of Wand Mo by using GDX-103 resin as the support and TOPO-xylene as the stationary phase. After eluting coexistent ions with 4 mol/L HC1-0. 05 mol/Ltartaric acid, Wand Mo are separated by elution with 1 mol/L HC1-0. 05 mol/Ltartaric acid and 0. 01 mol/Ltartaric acid. The method combined with SAF-CTMABspectrophotometry has been applied to determining Wand Mo in alloy steels and geochemical samples with satisfactory results.
