Chinese Abstract

研究了異丙氧基杯[4]冠-6(簡稱iPr-C[4]C6)正辛醇的萃取性能,主要考察了酸度、模擬高放廢液對萃取銫離子以及主要錒系元素和鍀的影響,初步研究了輻照劑量對iPr-C[4]C6/正辛醇萃取銫離子的影響。研究表明:水相中無模擬料液時,酸度對iPr-C[4]C6萃取銫離子的影響較大;除鉀離子外,其它共存離子對萃取銫離子的影響較小;有模擬料液存在情况下,酸度的影響較小,而稀釋倍數影響較大;輻照劑量小於10^5Gy時,體系對銫離子萃取無明顯影響。在硝酸溶液中,萃取體系對錒系元素的萃取率很低;有模擬料液時,除鎇和鍀外,其它元素的分配比明顯昇高。

English Abstract

The extraction capability of bis (2-propyloxy)-calix[4] 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 10^4~10^5Gy. 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.
