| Abstract: | 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. |
