Abstract
The copper(II), nickel(II), palladium(II) and oxovanadium(IV) chelates of N,N′-ethylenebis (1,1,1-trifluoro-6-methyl-2- oxoheptan-4-imine) (H 2TFIVA 2en) and N,N′-1,2-propylenebis(1,1,1-trifluoro-6-methyl-2-oxoheptan-4-imine) (H 2TFIVA 2pn) were eluted from gas chromatographic columns, but their copper and nickel chelates could not be resolved. The detection limits were found to be 4–40 ng for each metal chelate. The copper, nickel, palladium and oxovanadium chelates were separated on reserved-phase HPLC columns, Nova Pak C 18 (150 × 3.9 mm) and Microsorb C 18, (150 × 4.6 mm). Elution was obtained with a binary mixture of methanol-water or a ternary mixture of methanol-acetonitrile-water. Detection was achieved using a UV detector. Linear calibrations were obtained over the range 10–1200 ng and detection limits were 0.4–4.0 ng for the metal chelates.
