本文研究了从强放废液中综合提取锕系和镧系元素过程中Am(Cm)的测定。采用0.05 MPMBP-0.025MTOP/环己烷溶液协同萃取Am(Cm),以三倍于有机相体积的二甲苯稀释荷载有机相,再用0.05M DTPA-1.0M乳酸(pH=3,下同)溶液定量反萃Am(Cm)。在0.2MHDEHP/煤油和0.05MDTPA-1.0M乳酸萃取体系中将Am(Cm)与剩余镧系元素分离。最后制源,测定Am(Cm)α放射性强度。方法对样品中Am(Cm)的回收率为(97.0±5.4)%
In this paper, the determination of Am (Cm) during the comprehensive extraction of actinides and lanthanides from strong liquid waste was studied. Am (Cm) was co-extracted with 0.05 MPMBP-0.025M TOP / cyclohexane solution. The organic phase was diluted with three times the volume of xylene in the organic phase and washed with 0.05M DTPA-1.0M lactic acid (pH = Quantitative stripping solution Am (Cm). Am (Cm) is separated from the remaining lanthanides in a 0.2M HDPE / kerosene and 0.05M DTPA-1.0M lactic acid extraction system. The final source, determination of Am (Cm) alpha radioactivity. The recovery of Am (Cm) from the method was (97.0 ± 5.4)%
