Abstract: In this paper, the fluorescence properties of Tb(Ⅲ)-BPMPHD-CTMAB have been investigated. The stoichiometry of fluorescence and the influence of some factors on the system are discussed. Anew method for determination of Tb(Ⅲ) in this system is developed. The detection limit was observed to be 3. 0×10-11mol/L. Satisfactory results were obtained by the proposed method for determination of trace amount of Tb in several synthetic samples.
