Abstract: | It has been found that the Sm-BPMPHD-CTMAB ion association system shows a strong fluorescence intensity. In this system some rare earth ions, such as Lu3+, Y3+, Gd3+ and Tb3+, exert an evident fluorescence enhancement effect. The formation conditions of the system and the factors affecting the columinescence effect were studied in detail in order to determine trace amounts of Sm3+. Under optimum conditions a linear relationship was obtained between the fluorescence intensity and the Sm3+ concentration in the range of 5.0×10?8–8.0×10?6 mol·L?1. The detection limit of Sm3+ was 2.0×10?8 mol·L?1. The determination gave satisfactory results. |
