Rare earth element (REE) will have more higher economic value when it is separated from its mineral. Separation of REE from the mineral is quite difficult because of the similarity of physical and chemical properties of each element. Solvent Impregnated Resin (SIR) is a separation method by amobilizing ligand in a polymer resin. In this experiment, derivative compound of pyrazolone, 4-sebacoylbis (H2SbBP) has been synthesized as a chelating agent and been trapped into Amberlite XAD-16 through Van der Waals interaction. H2SbBP synthesized by Jensen method, colored soft brown, purification yield was 98,24% with melting point 134–136 oC, soluble in chloroform, and showed characteristic peak of pyrazolone derivative ring. Capacity of XAD-16 in absorbing ligand was 112.53 mg/g resin. La3+ extracted the most in pH 3. As a result, SIR-H2SbBP’s capacity in extracting La3+ using column method in 1 mL/minute flow was found to be 3.4655 mg/g SIR. Recovery yield by stripping La3+ with HNO3 0.1 M was 78.20%.
