Microchimica Acta Aims and scope Submit manuscript

Summary

Chrome Azurol S permits a simple colorimetric determination of palladium with a sensitivity of 0.4μg/cm2 (practical) or 0.04μg/cm2 (Sandell), respectively. Conditions and interferences are described in detail.

Zusammenfassung

Palladium läßt sich mit Hilfe von Chromazurol S auf einfache Weise kolorimetrisch bestimmen. Die praktische Empfindlichkeit der Methode beträgt 0,4μg/cm2 bzw. 0,04μg/cm2 nachSandell. Die Arbeitsbedingungen und die durch Fremdionen verursachten Störungen werden angegeben.

Résumé

Le chromazurol S permet un dosage colorimétrique simple du palladium, avec une sensibilité de 0,4μg/cm2 (en pratique) ou 0,04μg/cm2 (Sandell) respectivement. On décrit en détail les conditions opératoires et les interférences.
