Block copolymer micellization induced microphase mass transfer: Partition of Pd(II), Pt(IV) and Rh(III) in three-liquid-phase systems of S201-EOPO-Na2SO4-H2O

► The appearance of three liquid phases permits one-step separation of Pd, Pt and Rh. ► The phase behavior has a correlation with three-phase partitioning of Pd, Pt and Rh. ► Microphase interfacial structure is an important factor in mass transfer of metals.
