Copper(II), nickel(II), palladium(II) and oxovanadium(IV) chelates of bis(salicylaldehyde) tetramethylethylenediimine (H(2)SA(2)Ten) were separated on normal phase high performance liquid chromatographic (HPLC) column, Si 100, 5 mu. The chelates were eluted with a ternary mixtures of 1,2-dichloroethane: chloroform: acetonitrile (70:28:2, v/v/v). The detection was achieved using a spectrofluorimetric detector. The linear calibration range for each of the complex at optimized spectrofluorimetric detection were determined. A solvent extraction procedure in chloroform was examined for the determination of nickel and method was applied for the estimation of nickel in a nickel aluminum alloy.
