摘 要: 讨论了阴离子型表面活性剂(SDS)和阳离子型表面活性剂(CTMAB、Zeph 和 CPC)对 Ln^(3+)-β-二酮二元体系、Ln^(3+)-β-二酮-Phen(或 DPG)三元体系及 Tb^(3+)-AA-EDTA、Tb^(3+)-Tiron、Tb^(3+)-H_2Sal-EDTA 水溶性体系荧光光谱的影响,发现不同的表面活性剂对不同的反应体系影响不尽一致.增敏程度与表面活性剂和荧光配位体的结构有关。 The influence of ionic surfactants(SDS,CTMAB,Zeph and CPC)on fluo- rescence spectra of Ln^(3+)-β-diketone and Ln^(3+)-diketone-organic base and the readily soluable systems of Tb^(3+)-AA-EDTA,Tb^(3+)-Tiron and Tb^(3+)-H_2Sal-EDTA has been discussed in this paper.It has been observed that the influence of different surfactants on different fluorescent reactions is not the same.More- over,the sensitization and the degree of sensitization are also related to the structure of surfactant and ligand.
