The distribution ratios of U(VI), Np(V), Pu(IV) and Am(III) are measured by the single stage extraction experiments of simulated high-level liquid waste with 22%DHDECMP-42%TBP/OK. The extraction behavior of U, Np, Pu and Am in simulated high-level liquid waste is determined on miniature countercurrent centrifugal contactor cascade (6 stages for extraction, 2 stages for scrubbing, 6 stages for stripping, AF : AX : AS=1 : 1.5 : 0.5; BF : BX=1 : 1). The experimental results show that removal efficiency of U(VI), Np(V), Pu(IV) and Am(III) from simulated high-level liquid waste, all of them ,is equal or more than 99.9%. The stripping efficiency of U(VI),
