Abstract
Solvent extraction experiments of Rh(III) and Ir(IV) were performed on the HCl solution by using Alamine336 and TBP. The extraction percentage of Rh and Ir by Alamine336 was much higher than that by TBP. For the solvent extraction with Alamine336, the extraction percentage of Rh and Ir decreased with a HCl concentration. However, the extraction percentage of both metals by TBP was below 12% in our experimental range and increased with an increasing HCl concentration of up to 8 M. From the mixed solution of Ir with an excess SnCl$_{2}$, most of the tin was extracted by Alamine336 and TBP. However, the extraction percentage of Ir by Alamine336 was reduced and no iridium was extracted by TBP. The extraction behavior of Ir and Sn was investigated by scrubbing experiments on the loaded Ir with a SnCl$_{2}$ solution.
