Microchimica Acta Aims and scope Submit manuscript

Summary

Optimal conditions for the destruction of biological material in the determination of nano-amounts (ng = 10−9g) of iodine are described. The iodine-containing material is burned in oxygen on a platinum coil, and is absorbed over a period of 30 minutes in 0.66N Na2CO3. The standard deviation of this method is 4.9%.

Zusammenfassung

Geeignete Arbeitsvorschriften für die Zerstörung biologischen Materials für die Bestimmung von Nanogramm-Mengen Jod werden angegeben. Das jodhältige Material wird in einer Sauerstoffatmosphäre in einer Platindrahtspule verbrannt, die Verbrennungsprodukte werden innerhalb 30 Minuten in 0,66-n Sodalösung absorbiert. Die Standardabweichung der Methode beträgt 4,9%.

Résumé

On décrit les conditions optimales pour la destruction de la substance biologique dans le dosage de l'iode en quantités de l'ordre du nanogramme (1 ng = 10−9g). On brûle la substance contenant de l'iode dans l'oxygène et sur un rouleau de platine et on l'absorbe pendant 30 minutes dans Na2CO3 0,66 N. La déviation standard de cette méthode est de 4,9 %.
