Title: Preparation of actinides for. cap alpha. spectrometry without electrodeposition

Abstract

Procedures are described by which all ..cap alpha..-emitting elements except radium and polonium can be mounted in a form suitable for ..cap alpha.. spectrometry without need for electrodeposition. The actinides except uranium are precipitated as hydroxides with 50 ..mu..g of cerium carrier from a strongly alkaline solution of ethylenediaminetetraacetic acid. The precipitate is mounted on a 25-mm membrane filter with 0.1-..mu..m pore for spectrometry. The resolution is almost as good as that obtained by electrodeposition on polished stainless steel, and the yield is generally greater than 95%. Uranium can be prepared similarly for ..cap alpha.. spectrometry by reducing it to the quadrivalent state with titanium trichloride in dilute acid and precipitating uranous fluoride.
