Interfacial-specific chemiluminescence at liqud/liquid interfaces or at O/W emulsions containing lucigenin in oil phase

Abstract

The enhanced effect of chemiluminescence (CL) of lucigenin (Luc 2+ ) at a flat liquid/liquid interface and at O/W emulsions was demonstrated. The CL was emitted when Luc 2+ was transferred from an organic phase to an aqueous one containing NaOH and H 2 O 2 . The CL intensity and emission spectrum depended strongly on the kind of organic solvent. We attempted to apply the CL reaction of Luc 2+ in the O/W emulsion system to the analysis of H 2 O 2 . The available analytical conditions were discussed from the aspects of the kind of organic solvent, the reaction time and wavelength detected. © 2009 The Japan Society for Analytical Chemistry.
