摘　　要：系统地探讨了水杨酸乙、丁、戊酯—ＴｒｉｔｏｎＸ－１００体系荧光法测定Ｔｂ３＋、Ｄｙ３＋的最佳条件，发现Ｌｕ３＋或Ｇｄ３＋的共存能使Ｔｂ３＋、Ｄｙ３＋的特征荧光增敏。其中水杨酸丁酯—Ｌｕ３＋增敏体系的灵敏度最高，测定Ｔｂ３＋、Ｄｙ３＋的检测限分别达到０．２和８．０μｇ／Ｌ。应用本法成功地测定了Ｌｕ２Ｏ３、Ｇｄ２Ｏ３中０．Fluorimetric determination of Tb 3+ and Dy 3+ with Ethyl,Butyl,Armyl and Phenyl Salicylate-Triton X-100-Lu 3+ (Gd 3+ ) micellous system has been discussed.Butyl salicylate system is the most sensitive.The optimal conditions of fluorimetric determination of Tb 3+ and Dy 3+ have been proposed.The detection limit of Tb 3+ and Dy 3+ is 0.2 and 8.0 μg/L,respectively.Using the butyl salicylate system,the 0.00x% level of Tb 4O 7 in Lu 2O 3 and Gd 2O 3 have been successfully determined by a standard addition method.
