A method for vanadium speciation is proposed. The method uses a low concentration eluent, 10 mmol L-1 EDTA and 14 mmol L-1 sodium carbonate, for the ion chromatographic separation of vanadium species at a flow rate of 1.2 mL min-1. The quantitative detection limits were 0.14 mg L-1 for V(IV) and 0.20 mg L-1 for V(V) using ICP-OES detection. The method was successfully applied to the analysis of synthetic samples and mineral processing samples.
