The copper(II), nickel(lI) palladium (II) and vanadium (IV) oxide complexes of bis(isovaletylacetone)ethylenediimine (HzIYzAen) are prepared and eluted on OV1D1 and OV 17, 3% on Chromosort> SO-loo GC columns and separation between copper, nickel, palladium and vanadium is achieved. The reagent has been examined for the extraction of the metal ions in cyclohexane and the efficacy of the reagent for analytical utility is investigated with regards to gas chromatographic behaviour. Detection limits and calibration range of metal ions are reported.
