| Abstract: | The synergic extraction of lanthanide ions (La 3+ , Sm 3+ , Er 3+ ) from nitric acid solution into the mixture of 1 phenyl 3 methyl 4 acetyl pyrazolone 5 (PMAP) with 1,10 phenanthroline in trichloromethane is studied. The formula of synergic extraction compounds determined by slope analysis method is REA 3·B; the values of pH 1/2 of La 3+ , Sm +3 and Er 3+ (RE 3+ HA system) are 3.31, 2.86 and 2 61 separately. The solid synergic extraction compounds of Lanthanum are prepared and are characterized by elemental analysis. The IR spectra of the solid synergic extraction compounds are discussed. |
