摘要
研究了Ｌｕ３＋、Ｙ３＋、Ｓｃ３＋、Ｇｄ３＋、Ｌａ３＋等几种Ｌ＊－Ｌ发光型稀土离子与槲皮素－ＴＯＰＯ（ＴＸ－１００）－ＳＤＳ组成体系的荧光特性、影响因素及分析应用。于最佳条件下，测定上述稀土离子的最低检测限可达０．０１ｍｇ／Ｌ。探讨了ＴＯＰＯ（ＴＸ－１００）－ＳＤＳ对Ｌｎ－槲皮素二元体系的增敏机理。
The systems formed by Lu 3+ ,Y 3+ ,Sc 3+ ,Gd 3+ ,La 3+ which belong to L L type luminescence and quercetin TOPO(TX 100) SDS organic system were studied in detail on the fluorescence characteristics,affecting factors and analytical application. Under the optimum conditions, the detection limits of these RE ions were down to 0.01 mg/L. The enhancement mechanism of Ln quercetin binary system by TOPO(TX 100) SDS was discussed. The determination of Lu 3+ in the heavy rare earth sample was carried out by using the standard addition method.
