摘要：

The paper studies the stoichiometry and the fluorescence emitting mechanism of EU(3+), Tb3+ complexes with pyrazine-2, S-dicarboxylic acid. The optimum conditions of simultaneous determination for Eu3+, Tb3+ by derivative fluorometry are established. The interference of other ions is investigated. The detection limits of Eu3+, Tb3+ are 4.0 ng/mL and 2.0 ng/mL, respectively. This method for analyzing the amount of EU(3+), Tb3+ in rare earth samples has been proved to be satisfactory.
