Novel Extractant Calixcrown Used in High-level Liquid Waste (Ⅲ)——Extraction Capability of Bis(2-propyloxy)calix\crown-6/n-octanol

  • 摘要: 研究了异丙氧基杯 [4]冠 6(简称iPr C[4]C6) /正辛醇的萃取性能, 主要考察了酸度、模拟高放废液对萃取铯离子以及主要锕系元素和锝的影响, 初步研究了辐照剂量对iPr C[4]C6/正辛醇萃取铯离子的影响。研究表明 :水相中无模拟料液时, 酸度对iPr C[4]C6萃取铯离子的影响较大 除钾离子外, 其它共存离子对萃取铯离子的影响较小 有模拟料液存在情况下, 酸度的影响较小, 而稀释倍数影响较大 辐照剂量小于 1 0 5Gy时, 体系对铯离子萃取无明显影响。在硝酸溶液中, 萃取体系对锕系元素的萃取率很低 有模拟料液时, 除镅和锝外, 其它元素的分配比明显升高

     

    Abstract: The extraction capability of bis(2-propyloxy)-calix\crown-6/n-octanol was studied. The D(Cs) is strongly affected by acidity and dilution factor of simulated high-level liquid waste(SHLLW). There are little influences of other common ions except potassium. There is little change for D(Cs) in the range of the radiation dose 10~4~10~5 Gy. The distribution ratios of actinides are very low when aqueous phase is nitric acid. They distinctly increase when the aqueous phase is SHLLW except americium and technetium.
