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

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.
