A hydrophobic ionic liquid including an amino moiety ([DiOcAPmim][NTf2]) was synthesized. Itsextraction behaviors towards Pd(II), Ru(III), Rh(III) were investigated in nitric acid aqueous solution as afunction of contact time, effect of concentration of nitric acid, effect of temperature, and effect of coexistingmetal ions. The extraction kinetics of Pd(II) was fairly fast and extraction equilibrium can beattained within only 5 min under the [HNO3] ¼ 2.05 M. When [HNO3]< 1 M, the extraction percentage ofPd(II), Ru(III), Rh(III) were all above 80%. When [HNO3] reached 2 M, all of the extraction percentagedecreased and in an order of Pd(II)>Ru(III)>Rh(III). When [HNO3]> 2 M, the extraction performancegradually recovered. The effect of temperature can slightly affect the extraction performance of Pd(II). Furthermore, in simulated high-level liquid waste, [DiOcAPmim][NTf2] showed a better preference towardsPd(II) under the interference of various other co-existing metal ions
