N-癸酰吗啡啉(DMPHL)萃取铕(Ⅲ)的热力学研究

Thermodynamitic Study of the Extraction of Eu(Ⅲ) by N-decanoylmorpholine

合成了新型萃取剂N—癸酰吗啡啉(DMPHL),研究了该萃取剂对三价铕的萃取性能,试验结果表明该萃取剂对Eu(Ⅲ)有一定的萃取能力,并讨论了酸度、温度、盐析剂等多种条件的影响。

A new kind of amide extractant N - decanoylmorpholine （ DMPHL ） has been prepared at the first time and it＇ s extraction performance to Eu （ Ⅲ ） has been tested. The experimental results show that DMPHL has extraction efficient to Eu （Ⅲ ）, and aqueous nitric acid concentration, concentration of extractant, temperature and concentration of salting - out agent have effection to D.
