双亚砜与TBP对铀(Ⅵ)萃取行为的比较

COMPARISON OF EXTRACTION OF U(Ⅵ) FROM NITRIC ACID BY DISULFOXIDES AND TBP

摘要: 合成了 6种双亚砜萃取剂RSO(CH2 ) nSOR(n =4 ,6 ;R =CH3 (CH2 ) 2 CH2 — ,CH3 CH(CH3 )CH2 CH2 — ,CH3 (CH2 ) 3 CH(C2 H5)CH2 — )。研究了这 6种双亚砜 /CHCl3 对铀 (Ⅵ )的萃取性能 ,并与TBP/CHCl3 作了比较。实验结果表明 ,6种双亚砜萃取剂对铀 (Ⅵ )的萃取能力均优于TBP。

Abstract: Six kinds of disulfoxides (RSO(CH 2) n SOR( n =4,6; R=CH 3(CH 2) 2CH 2 -,CH 3CH(CH 3)CH 2CH 2 -,CH 3 (CH 2) 3CH(C 2H 5)CH 2 -) are synthesized. The extraction of uranium(Ⅵ) from nitric acid solution by disulfoxides is studied and compared with that by TBP. The experimental results show that their extracting ability is superior to that by TBP.
