Summary

Palladium chloride was determined spectrophotometrically withβ-ethylthioethylenethioglycolic acid (β-ETETGA) and ethylene-bis-thioglycolic acid (EBTGA) in acid medium. The Pd-β-ETETGA system obeys Beer's law in the range 0.5–5.0μg/ml and Pd-EBTGA system obeys Beer's law in the range 0.4–8.0μg/ml. Determination of palladium in presence of many “associated metals” and many anions is reported.

Zusammenfassung

Palladiumchlorid läßt sich mitβ-Äthylthioäthylenthioglykolsäure bzw. mit Äthylen-bis-thioglykolsäure in saurem Medium spektralphotometrisch bestimmen. Das erstgenannte Reaktionssystem folgt zwischen 0,5 und 5,0μg Pd/ml, das andere zwischen 0,4 und 8,0μg Pd/ml dem Beerschen Gesetz. Über die Bestimmung von Pd in Gegenwart zahlreicher Begleitmetalle und vieler Anionen wurde berichtet.
