The separation between copper, nickel and palladium complexes of bis(O-hydroxyacetophenone)ethylenediimine has been achieved, on a stainless steel column (2.6mm x 250mm) packed with aluminium oxide (LiChrosorb Altox T 5f.lm). The complexes were eluted with 60:40 chloroform:n-hexane solvent-1 system wlth the flow rate of 1.5ml mln and the absorbance was measured atX 260nm us i ng a UV detector. The 1 i nea r cali bra t i on range wi th detect i on limits for copper, nickel and palladium complexes at lower ng levels have been ascertained.
