二环已基-18-冠-6和二-(2-乙基已基)磷酸对六价铀的协同萃取

THE SYNERGISTIC EXTRACTION OF URANYL ION BY DI (2-ETHYLHEXYL)PHOSPHATE (HDEHP) AND DC18C6(B).

摘要: <正> 自Blake在研究二-(2-乙基已基)磷酸从硫酸的矿浆溶液中萃取铀时发现协同效应以来,已有许多作者用含磷试剂对铀的协同萃取进行了广泛研究。关于冠醚化合物协同萃取铀的工作,至今未见报道。

Abstract: The synergistic extraction of uranyl ion from inorganic acid (HNO3, HC1 and H2SO4) into nitrobenzene by DC18C6 and HDEHP is studied. Experimental results indicate that the synergistic extraction reaction is as follows :The estimated values of the equilibrium constants K12 of the synergistic extraction reaction respectively are 4.85×106, 2.39×10s and 1.91×105 in the nitric, hydrochloric and sulphuric acid solutions.
