Abstract
The thermoanalytical and gas chromatographic behaviour of the copper(II), nickel(II), zinc(II), cadmium(II), palladium(II) and platinum(II) chelates of 4,4′- (ethane-1,2-diyldiimino)bis(pent-3-ene-2-thione) and the copper(II) and nickel(II) chelates of 4-[(3-oxo-1-methylbut-1-enyl)aminoethylamino]pent-3-ene-2-thione are reported here for the first time. With exception of the cadmium chelate, the derivatives elute as sharp, symmetrical peaks at microgram levels without extensive decomposition. Detection limits with flame ionization detection were in the range 0.2–1.5 ng of metal. A nearly complete separation of five chelates of the first ligand is demonstrated. The use of this reagent for the simultaneous determination of copper, nickel and zinc has been examined.
