SYNERGISTIC EXTRACTION OF URANIUM (VI) WITH 1,10-BIS (1'-PHENYL-3'-METHYL-5'-OXOPYRAZOLE-4'-YL) DECANEDIONE-1,10 AND 1,10-PHENANTHROLINE

摘要: 研究了1,10-双(1′-苯基-3′-甲基-5′-氧代吡唑-4′-基)癸二酮-1,10(BPMPDD,简作H_2A)与110-二氮杂菲(Phen)从盐酸溶液中对铀的协同萃取行为。经斜率法测定萃合物的组成为UO_2A·Phen协萃平衡常数(K_(se))59.31。用萃取法制得了固态配合物,对其溶解性、摩尔电导、热稳定性及UVIR、~1HNMR谱进行了研究。讨论了协萃机理及萃合物的可能结构。

Abstract: Synergistic extraction of UO22+ with 1,10-bis(1'-phenyl-3'-methyl-5'-oxopyrazole-4'-yl)decane-dionel-1,10 and 1, 10-phenanthroline has been investigated. The composition of the extractive and equilibrium constant of the synergistic extraction have been determined. The solubility, molar conductance , thermal stability, UV, IR, and 1HNMR spectra of the solid extractive have been discussed. The synergistic extraction mechanism and the possible structure of the complex have been suggested.
