Abstract

A new approach for extraction of ⁹⁹Mo tracer as a lighter homolog of Seaborgium (Sg) by three different the ionic liquids are studied. Aliquat-336 [Aliq-336.Cl^-] as anion exchange has been used for the preparation of three ionic liquid, namely: ([Aliq-336]⁺ [SCN]^-), ([Aliq-336]⁺ [S]^- ) and ([Aliq-336]⁺ [Fe(CN)₆]^-). Their potential extraction of carrier free ⁹⁹Mo from HNO₃ solutions has been evaluated. The obtained results demonstrated that successful extraction of carrier free ⁹⁹Mo from HNO₃ solutions is achieved. The ([Aliq-336]⁺ [Fe(CN)₆]^-) is found to give the highest extraction affinity for ⁹⁹Mo than the others ionic liquids investigated. The preliminary results could be useful for the upcoming aqueous experiments of Seaborgium.
