吡啶-2,6-二羧酸体系荧光法同时测定地质和环境试样中的钐、铕、铽、镝
SPECTROFLUOROMETRIC DETERMINATION OF SAMARIUM, EUROPIUM, TERBIUM AND DYSPROSIUM IN GEOLOGICAL AND ENVIRONMENTAL SAMPLES WITH PYRIDINF-2,6-DICARBOXYLIC ACID
【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。
【Abstract】 The optimum conditions for the fluorometric determination of Sm3+, Eu3+,Tb3+ and Dy3+ with Pyridine-2.6-dicarboxylic acid and the effect of coexisting ions have been investigated. Sm3+, Eu3+, Tb3+, Dy3+ in geological and environmental samples were separated and simultaneously determined with strong acidic cation exchange resin method and this fluorometric method.
