Abstract
The synergistic extraction of tracer amount of Am(Ⅲ) and Eu(Ⅲ) from nitrate medium with purified Cyanex 301(HBTMPDTP) and TBP in kerosene is studied.The distribution ratios of Am(Ⅲ) and Eu(Ⅲ) vary with TBP concentration in organic phase and pH value in aqueous phase.While pH>2.5,the separation coefficient is more than 200 which is large enough for the separation of Am(Ⅲ) from Eu(Ⅲ).
