摘要
用同位素示踪法研究了冠醚对模拟高放废液中Sr^(2+)、Cs~+的提取。0.01mol/l二环己基-18-冠-6在CHCl_2CHCl_2和CHCl_3中对Sr^(2+)的一次萃取率在90%以上。二苯并-21-冠-7-磷钼酸-硝基苯体系对Cs~+的萃取效果较好。
The extraction of Sr ̄(2+)and Cs ̄+ in simulated high level radioactive liquid waste with crown ethers is studied by the radioisotopiac trace,The first extraction rate of Sr ̄(2+)with 0.01mol/l dicyclohexyl-18-crown-6 in 1,1,2,2-tetrachloroethane and trichlo romethane is more than 90%.The results show that Cs ̄+ can be extracted effectively by dibenzo-21-crown-7-H_3PMo_(12)O_(40)(3/1)in nitrobenzene.
