【摘要】本文合成了对叔丁基杯[8]酮衍生物(H8L′),通过元素分析、红外和13C核磁共振谱表征了H8L′,并推测了其结构。通过改变H8L′的浓度,萃取酸度,稀土金属浓度以及溶液的离子强度,研究了对叔丁基杯[8]酮衍生物对稀土金属离子Nd3+、Pr3+、Eu3+的萃取性质,探讨了对叔丁基杯[8]酮衍生物萃取稀土金属离子的机理。更多还原

【Abstract】 In this paper,the p-tert-butylcalix[8]arene ketone derivative(H8L′) was synthesized,and characterized by elemental analysis,infrared spectra and 13C NMR.The properties for H8L′ extracting with rare earth Nd3+,Eu3+ and Pr3+ was studied through change of H8L′ concentration,extraction acidity,solution ionic strength and concentration of rare earth metals.The mechanism for H8L′ extracting with rare earth ions was also further discussed.更多还原
