Aggregates (mixed micelles, bilayer membranes, vesicles) formed from aqueous mixtures of dodecyltrimethylammonium chloride (DTAC) and sodium dodecyl sulfate (SDS) were evaluated for chemiluminescence (CL) reaction media by means of a batch method. The uranine CL based on oxidation by hypochlorous acid was chosen as a model CL system. The uranine CL intensity was enhanced by a factor of 91 in mixed micelles ([DTAC]/[SDS]=1.5) compared with that in other aggregates (bilayer membranes and vesicles). This enhancement is thought to be caused by the increased CL quantum yield, which results from stabilization of the emitter (uranine) on the interface of the rigid mixed micelles.
