“…Gandon et al [10] co-precipitated ruthenium with copper ferrocyanide neutral solution. D. Banerjee et al [11] used conventional ion exchangers and chemical precipitation based processes for the effective removal of the 106 Ru activity from NH 4 NO 3 effluent generated during wet processing of rejected sintered depleted uranium fuel pellets.…”

An effective and simple process for the isolation of 106Ru from high-level liquid wastes was developed. Radioactive ruthenium was oxidized by H5IO6 in HNO3 solution and was extracted to CCl4 phase in the form of RuO4. In order to obtain ruthenium in the suitable form for production of brachytherapy sources, RuO4 in organic phase was reduced and re-extracted to aqueous phase. The efficiency of extraction of 103Ru to organic phase was 86 %, re-extraction to aqueous solution was near 100 %, so the overall recovery of 103Ru is estimated at more than 80 %.
