Third phase formation in the extraction of Nd(III) by Octyl(Phenyl)-N,N-Diisobutyl Carbamoyl methyl phosphine oxide (O phi CMPO)

Third phase formation in the extraction of Nd(III) by 0.2 M Octyl(Phenyl)-N ,N-Diisobutyl Carbamoyl methyl phosphine oxide (O Phi CMPO) in n-dodecane h as been studied with tri-n-butyl phosphate (TBP) and tri-n-amyl phosphate ( TAP) as modifiers to provide a comparison between these two modifier system s. The effect of concentration of TAP as modifier for the extraction of Nd( III) by 0.2 M O Phi CMPO has been studied. The extraction of Nd(III) by TAP /n-dodecane in the absence of O Phi CMPO has also been studied and the resu lts are reported here.
