nitrate hydrates ([Ln(κ2-NO3)3·nH2O]) were dissolved in the presence of tributylphosphate (O═P(O(CH2)3CH3)3) referred to as TBP) in kerosene or triphenylphosphate (O═P(O(C6H5) referred to as TPhP) in acetone. The crystal structure of the TPhP derivatives of the lanthanide nitrate series and uranium nitrate were solved as [Ln(κ2-NO3)3(TPhP)3] (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu)
在搜索用于从钚铀氧化还原萃取(PUREX)处理烧伤,一系列硝酸镧系元素水合物([LN(气雾剂铀废产物合适的模拟物的κ 2 - NO 3)3 · Ñ ħ 2 O])溶解在存在煤油中的磷酸三丁酯(O═P(O(CH 2)3 CH 3)3)称为三丁酸酯或丙酮中的磷酸三苯酯(O═P(O(C 6 H 5)称为TPhP))的晶体结构硝酸镧系和铀硝酸的TPhP衍生物就解决了为[LN(κ 2 - NO3)3(TPhP)3 ](LN =的La,Ce的,镨,钕,钐,铕,钆,铽,镝,何,铒,的Tm,镱,路)和[U(O)2(κ 2 - NO 3)2(TPhP)2 ](U)。镧系元素-TBP,Ln和U使用FTIR光谱,31 P NMR光谱,热重分析和X射线荧光光谱进一步表征。此外,通过PXRD分析发现使用箱式炉模拟热解条件对镧系元素TBP,Ln和U进行热处理,以生成所有系统的磷酸盐相(LnP 3 O 9或UP 2 O
