Abstract: The fluorescence system of Dy(,)-BPMPI-ID-CTMAB was studied. It was found that Dy'+couldform an ion association complex with BPMPHD and CTMAB and then emitted the intrinsic fluorescenceof Dy'+. The fluorescence intensity of the system could be increased by Gd'+,Y"" ,La'+. This is a newlyfound Co-luminescence system. Based on the Co-luminescence system,a rapid, simple and sensitivemethod was developed for the determination of trace amounts of Dy'+. The results indicated that the flu-orescence intensity of the system is a linear relationship with the concentration of Dy'+ in the range of1. 0 X 10-,一1.3X10-Smol/L,thedetectionlimit (SlN=2) is 2.0X10-0mol/L.
