Abstract

Abstract: The conditions for the spectrophotofluorometric determination of terbium and europium, in solutions of potassium carbonate, have been established. The apparent excitation and fluorescence wavelengths used, respectively, are 245 mμ and 550 mμ for terbium and 400 mμ and 620 mμ for europium. The fluorescence varies linearly with the concentration of terbium and europium in the range 0.3–70 μg, of terbium/ml and 4–800 μg of europium/ml. Large amounts of gadolinium, lutetium and yttrium do not interfere. Cerium(IV) interferes seriously.

Large amounts of gadolinium, lutetium and yttrium do not interfere. Cerium(IV) interferes seriously.</abstract>
<abstract lang="fr">Résumé: On a établi les conditions de dosage spectrophotofluorométrique du terbium et de l'europium en solutions dans le carbonate de potassium. Les longueurs d'onde moyennes d'excitation et de fluorescence utilisées respectivement sont de 245 mμ et 550 mμ pour le terbium, et 400 mμ et 620 mμ pour l'europium. La fluorescence varie linéairement avec la concentration entre 0,3 et 70 μg ml pour le terbium et 4 et 800 μg ml pour l'europium. De fortes quantités de gadolinium lutétium et yttrium n'interfèrent pas. Le cérium(IV) interfère sérieusement.</abstract>
<abstract lang="de">Zusammenfassung: Die Bedingungen zur spektrofluorimetrischen Bestimmung von Terbium und Europium in Kaliumcarbonatlösung wurden ermittelt. Als Anregungs- und Fluoreszenzwellenlängen wurden 245 mμ und 550 mμ für Terbium und 400 mμ und 620 mμ für Europium verwendet. Die Fluoreszenzintensität ändert sich linear mit der Konzentration im Bereich von 0,3–70 μg ml Terbium und 4–800 solμg ml Europium. Große Mengen Gadolinium, Lutetium und Yttrium stören nicht, Cer(IV) dagegen stark.</abstract>
