description

Losungsmittelextraktionen lassen sich erheblich beschleunigen, indem man das Extraktionsmittel an einen feinkornigen TrAger adsorbiert und die zu extrahierende Losung rasch durch eine dunne Schicht dieses Materials saugt. Funfwertiges Antimon und Protactinium werden durch Diisobutylcarbinol und Di-2-Athylhexyl-orthophosphorsAure, gebunden an PolytrifluormonochlorAthylen, selbst bei maximaler Sauggeschwindigkeit von 2–3 ml/sec nahezu quantitativ extrahiert. Die Anwendung dieser Technik bei kernchemischen Studien wird an folgenden schnellen Trennungen demonstriert: Protactinium-234 m aus Uran, Antimon aus Tellur nach (n, p)-Proze\, Antimon aus Spaltprodukten und wiederholtes Abmelken von Tellur aus Spaltantimon.
