溶剂萃取中采用混合萃取剂所产生的协同效应,已获得了广泛的研究.特别是以螯合萃取剂与中性萃取剂组成的协同萃取体系,更引起人们的重视.Cvjeticanin将纸上反相分配色谱用于协萃效应的研究.选用螯合萃取剂噻吩甲酰三氟丙酮(TTA)与中性磷类萃取剂磷酸三丁酯(TBP)、三辛基氧化膦(TOPO)或磷酸三辛酯(TOP)组成的混合萃取剂作固定相,研究了对铀、钍和稀土元素的协萃效应,并探讨了有关的协萃机理.

The ohromatograghio behaviours of UO22 and various metallio ions have been investigated on paper impregnated with 8-hydroxyquinoline(HOx) or tributyl phosphate(TBP) reapeotively, and with a mixture of both extraotanta, eluted with NaOAo-HCl buffer solution at pH 1.15-4.36. A synergistio effect waa apparent in the behaviour of UO22+with TBP-HOx system, and the expected agreement with the corresponding solvent extraction data was obtained.
