Summary
Plutonium(IV) forms a Chlorophosphonazo III complex in 0.5–2M hydrochloric acid. Maximum absorbance occurs at 620 and 685 nm. Beer's law is obeyed over the range of 0–50μg per 10 ml and the molar absorptivity is 3.7×104 mol−1 cm−1 at 690 nm. Plutonium can be determined in the presence of fluoride, sulfate and phosphate. However, lanthanides, thorium, uranium and zirconium interfere seriously.
Zusammenfassung
Plutonium(IV) bildet in 0,5-bis 2-m Salzsäure mit Chlorphosphonazo III eine Komplexverbindung, deren Absorptionsmaxima bei 630 und 685 nm liegen. Bis 50 μg/10 ml entspricht die Farbe dem Beer'schen Gesetz; die molare Extinktion bei 690 nm beträgt 3,7·104l·Mol−1·cm−1. Plutonium kann damit in Gegenwart von F−, SO4 2− und PO4 3− bestimmt werden. Lanthanide, Th, U und Zr stören jedoch ernstlich.
