Abstract

A chemical procedure is outlined for super-heavy element searches in irradiated uranium targets. The separation scheme is based on the wide range in stability and extractability of chlorometallic complexes by alkyl tertiary and quaternary ammonium chlorides and the wide range of extractability of metal ions by di-2-ethylhexylorthophosphoric acid. These two properties are utilized in various extraction chromatographic systems. The procedure was developed using elements in the sixth period as chemical homologues of super-heavy elements and tested on 100–200 mg irradiated uranium targets. The separation schemes are also applicable to other irradiated targets.
