- W2565431331 abstract "本文研究了PMBP-CHCl 2 与Ln(NO 3 ) 3 -H 2 O(Ln=La、Ce、Eu、Yb和Lu)的作用。发现,当PMBP浓度≥0.2M时,分配比与氢离子浓度的三次方成反比,与PMBP浓度的四次方成正比,全部稀土离子以LnA 3 ·HA;形式被萃入有机相,其萃取平衡常数(lgK)分别为La(-6.20)、Ce(-4.30)Eu(-3.62)、Yb(-2.90)及Lu(-3.20)。在萃取条件下,除Pm未经研究外,其余三价稀土元素经萃取后,从有机相都获得了与PMBP形成的固态络合物,其组成除Lu外均为LnA 3 ·HA,并对它们的晶形、红外光谱和热谱进行了研究。" @default.
