Abstract
The effect of aqueous solutions of cationic surfactants such as hexadecyltrimethyl ammonium hydroxide (CTAOH), hexadecyltrimethyl ammonium bromide (CTABr), anionic micelles of sodium lauryl sulphate (SLS), and nonionic micelles of polyoxyethylene(23) dodecanol (Brij-35), upon the lucigenin chemiluminescent reaction system with isoprenaline was evaluated. A lowering of the chemiluminescence (CL) emitted from the chemiluminescence reaction of lucigenin with isoprenaline was observed in cationic and anionic micellar assemblies. In contrast, an enhancement of the CL emission was observed in the presence of nonionic micelles of Brij-35. An account is given of the practical application of the surfactant effect.
