Abstract
A method involving a dual normal-phase/ion-exchange mechanism, preconcentration and separation of copper cyclohexanebutyrate, copper tetramethylheptanedionate and N,N′-disalicylidene-1,2-propylenediaminocopper on the polymeric stationary phase poly(vinyl alcohol) using a ternary gradient of 2-propanol, acetonitrile and 10 m M KCF 3SO 3, in methanol was developed. Copper compounds with formation constants of 10 20 or greater in water were retained via a normal-phase mechanism, whereas copper compounds with formation constants of 10 15 or less were retained via an ion-exchange mechanism. The method was used to characterize and to determine copper compounds with a limit of detection of 10 μg/1. The developed method was used to monitor the five classes of copper complexes formed when jet fuel samples with and without DuPont Metal Deactivator (DMD), the active ingredient of which is N,N′-disalicylidene-1,2-propylenediamine, were placed in contact with a metallic copper surface.
