【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. A new method for determination of Tb(Ⅲ) in this system is developed. The detection limit was observed to be 3. 0×10-11 mol/L. Satisfactory results were obtained by the proposed method for determination of trace amount of Tb in several synthetic samples.更多还原
