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等。本法与阳离子交换树脂联用,分离测定了地质和环境试样中的钐、铕、铽、镝含量。
The optimum conditions for the fluorometric determination of Sm^(3+), Eu^(3+),Tb^(3+) and Dy^(3+) with Pyridine-2.6-dicarboxylic acid and the effect of coexisting ions have been investigated. Sm^(3+), Eu^(3+), Tb^(3+), Dy^(3+) in geological and environmental samples were separated and simultaneously determined with strong acidic cation exchange resin method and this fluorometric method.
