研究了1-苯基-3-甲基-4-苯甲酰基吡唑酮-5(PMBP)萃取HNO_3溶液中镅、钚的性能,研究了水相酸度、相比(有机相∶水相)、萃取次数、萃取剂浓度等对PMBP萃取性能的影响.实验结果表明,在酸度为2 mol/L、相比为1∶1时,0.1 mol/L PMBP-二甲苯对分析样品进行一次萃取一次洗涤即能有效的分离大量钚,满足α能谱对微量镅的测定.该方法钚与镅的分离系数约为10~6,在C(Pu)/C(Am)≥10~6时对Am的相对偏差不大于8%.

The effect of the acidity in aqueous phase, phase-ratio, times of extraction and concentration of extractant on the extraction of Pu(Ⅳ) and Am(Ⅲ) from nitric acid solution by 1-phenyl-3-methyl-4-benzoylpyrazolone-5(PMBP) in organic solution were studied. The results show that the optimum conditions of Pu and Am a single washing. The separation factor between Pu and Am(SF(Pu/Am)) is about 10~6. The relative deviation for determination of Am is no more than 8% when C(Pu)/C(Am) is no less than 10~6.
