摘　　要：本文详细研究了Dy(Ⅲ)-1,6-双(1′-苯基-3′-甲基-5′-氧代吡唑-4′-基)己2酮-[1,6](BPMPHD)-溴化十六烷基三甲胺(CTMAB)体系荧光性质,探讨了荧光体系的组成比及影响体系荧光性质的诸因素,建立了在该体系中测定Dy(Ⅲ)的新方法。该体系中Dy(Ⅲ)的检测限可达到2.0×10^(-9)mol/L,应用于合成样品中微量Dy(Ⅲ)的测定,取得了满意的结果。In this paper, the fluorescence properties of Dy (Ⅲ)-1,4-his (l′-phenyl-3′-methyl-5′-oxopyrazole-4′)hexanedione-cetyltrimethyl-ammonium bromide have been investigated. The stoichoimetry of fluorescence and the influence of some factors on the system are discussed. A new method for the determination of Dy(Ⅲ)in this system is developed. The detection limit was observed to be 2.0×10^(-9)mol/L. Satisfactory results were obtained by the proposed method for determination of trace amount of Dy in several synthetic samples.
