三、协同效应早在1954年有人发现噻吩甲酰三氟丙酮和TBP的苯溶液对镨和敛的萃取能力比它们分别使用时有显著地增加,但当时并未引起人们注意.随着核燃料萃取化学的发展,1956年有人用D_2EHPA萃取铀时发现,当加入TBP,铀的分配比显著增加,从而提出了协同效应(或协同萃取)这一概念,并日益得到人们的重视. Third, the synergistic effect As early as 1954 was found that the benzoyl thioacyl trifluoroacetone and TBP benzene solution praseodymium and convergent extraction capacity than they were used when significantly increased, but did not draw attention at that time.With the nuclear fuel extraction In 1956, when D 2EHPA was used to extract uranium, it was found that the concept of synergistic effect (or synergistic extraction) was proposed when the addition of TBP increased the distribution ratio of uranium and gained increasing attention.
