For the development of a simple and rapid analytical method for actinides (Thorium, Uranium, Neptunium, Plutonium, Americium and Curium) in radioactive wastes, capillary electrophoresis-laser -induced fluorescence detecting method (CE-LIF) was studied. In this research, newly synthesized eight probes whose chelating group were acyclic or macrocyclic were applied to the detection of actinides using CE-LIF. As a result, Thorium and Uranium were successfully detected and separated from other actinide ions applied to octadenate acyclic probe and tetradenate planer probe, respectively. Neptunium was detected using hexadenate or heptadenate probes whose chelating groups were acyclic or macrocyclic. Plutonium was detected applied to hexadenate or octadenate acyclic probes. Americium and Curium were detected applied to seven probes except for tetradenate planer probe.
