The Fluorescence Properties of Tb(Ⅲ)-BPMPHD-CTMAB System and Its Analytical Applications
【摘要】 研究了Tb(Ⅲ)-BPMPHD-CTMAB体系的荧光性质,探讨了荧光体系的组成及影响因素,建立了在该体系中测定Tb(Ⅲ)的新方法。检测限可达到3.0×10-11mol/L,应用于合成样品中微量Tb(Ⅲ)的测定,结果满意。
【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.
