摘要
合成了四种双亚砜PhSO(CH2 )nSOPh(n =2 ,3,4,6)的铀酰配合物 ,经分析测试确定配合物的组成为UO2 ·L(NO3 ) 2 ,同时研究了配合物的部分性质 .结果表明 ,n =2的双亚砜与铀酰形成聚合物不能作萃取剂 ,n =3,4,6形成螯合物 。
The synthesis and characterization of four dioxouranium(VI) complexes with disulfoxides are reported. All these complexes yellowish powder have constant stoichiometry UO 2(NO 3) 2·PhSO(CH 2)nSOPh ( n =2,3,4,6). All of the complexes are characterized by element analysis and FT IR spectra. The extracting of dioxouranim(VI) from nitric acid solution by disulfoxide PhSO(CH 2)nSOPh( n =2,3,4,6) trichloromethane was studied. Results show that the laws of extracting dioxouranim(VI) by and disulfoxide are similar to that by tri n butyl phosphate(TBP) and extracting ability have advantaged over that by tri n butyl phosphate(TBP).
