摘　　要：本文研究了吡啶-2,6-二羧酸体系荧光法同时测定钐、铕、铽、镝的最佳条件及共存离子的影响。其检测限分别为3.0、0.15、0.09和0.5mg/mL。本文采用荧光法与阳离子交换树脂分离法联用,同时测定了地质和环境试样中的杉、铕、铽、镝含量。The optimum conditions for the fluorometric determination of Sm^(3+),Eu^(3+),Tb^(3+) and Dy^(4+) with pyridine-2,6-dicarboxylic acid and the effect of coexisting ions have been investigated. The detection limits of Sm^(3+), Eu^(3+),Tb^(3+) and Dy^(3+) are 3.0,0.015,0.09 and 0.5ng/mL,respectively. Sm^(3+),Eu^(3+),Tb^(3+) and Dy^(3+) in geological and environmental samples were separated and simultaneously determined with strongly acidic cation exchange resin and fluorometric method.
