Summary:adsorptive separation of rhenium and rhodium was performed by using a jacketed glass column packedwith an extractant impregnated resin (EIR). The EIR bed showed a successful separation of rhenium and rhodium withabout 12 BV of a breakthrough volume. The breakthrough behavior in the column was modeled to assess the masstransfer resistances in the column. The model predicted the column dynamics for rhenium quite well by assuming a7 cm2/min.The EIR loaded beds could be eluted with a high purity of more than 99% by using a nitric acid solution.
