  • Title: Enhanced chemiluminescence in the oxidation of luminol and an isoluminol cortisol conjugate by hydrogen peroxide in reversed micelles.

    Abstract:
    The chemiluminescent oxidation of luminol and an isoluminol cortisol conjugate (ABI-COR) by hydrogen peroxide has been studied in cetyltrimethylammonium bromide (CTAB) reversed micelles in octane-chloroform (1:1). The maximum chemiluminescence intensity of both compounds is dependent on the initial concentrations of the H2O2 and substrates, the pH value of the micelle polar phase and the H2O/CTAB ratio. The optimum pH ranged from 8.5 to 9.5. Under comparable conditions, the chemiluminescence intensity for luminol was 15-fold higher than for the ABI-COR conjugate. A mechanism of oxidation of the substrates in reversed micelles is proposed and the possible mechanisms of inhibition by the substrate and oxidant is discussed.
