Abstract
Abstract A novel chemiluminescence system, didodecyldimethylammonium bromide-uranine-sodium hydroxide, is described for the determination of ultratraces of free cyanide by flow injection method. Organized surfactant assemblies(bilayer vesicles) incorporated with a sensitizer (uranine) permit the determination of free cyanide very selectively with a limit of determination of 1 pg (20-μ1 sample injection). Sulfide, the strongest CL inducer after free cyanide, provides a signal 0.1 % of that for free cyanide.
