Palladium will be most increased demand in rare metals because the use of electrical and electronic fields in the future. Therefore, it is nesessary to construct the stable supply of resource in our country. Currently, the separation and recovery of palladium from urban mines have trying to carry out the solvent extraction method using the dihexylsulfide (DHS) extractant as the mainstream. However, DHS have some problems which the extraction process is lengthening because DHSs extraction rapid is so slowly. In this study, it was focused that triphenylphosphine (TPP) as an alternative DHS extractant. TPP shows the extraction rapid is about 5-6 times higher than DHS extractant. Therefore, we have been investgating to establish the Palladium separation and recovery process using TPP extractant. In our previous work, it was found that the multistep extraction is possible to separate Pd(II), Au(III)and Ni(II) from the coated electronic parts waste which use Cu as base material using TPP extractant. In this work, we investigated that the separation and extraction behavior of Pd(II), Au(III), Ni(II) and Cu(II) using TPP extractant. Furthermore, we considered that the separation and recovery process from the coated electronic parts waste by the extraction method with TPP extractant.
