摘要
4,4'-癸二酰一双(1-苯基-3-甲基-吡唑酮-5)(简称DBPMP,H_2A )是一种具有四个配位原子的螫合萃取剂,比PMBP多一倍的螯合功能团,它对稀土元素的分离能力和萃取能力大于PMBP,发现1,10-邻二氮菲(Phen )或三辛基氧膦(TOPO)
4, 4'- decanedioyl-bis- (1-pheny1-3-methy1-5-pyrazolone)(DBPMP) was one of a series of bis acelafed pyrazolone clelateextractants. In this paper, synergistic extraction by DBPMP and 1,10-phenanthroline or tri-n-octylphosphioxide(simplified as B) for Europiumin chlorofrom has been investigated.According to the slopes of lgD_(12)lg[H_2A], lgD_(12)～lg[B] and lgD_(12)～pH, compositions of the synergisticextracted compounds have shown to EuA·HA·B and the extractionequlibrium constants has been calculated, and the charateristics of solidsynergistic extracted compounds were studied by IR, UV, TG-DTA.
