摘　　要：研究了1-苯基-3-甲基-4-乙酰基吡唑酮-5(PMAP或HA)与1,10菲绕啉(Phen或B)对La3+,Sm3+,Er3+的协同萃取行为.用斜率法测定协萃合物的组成为REA3·B,测定HA对La3+,Sm3+,Er3+的pH1/2分别为3.31,2.86,2.61;对固态协萃合物的IR谱进行了讨论.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.
