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<sub>2</sub>A）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<sub>2</sub>A·Phen协萃平衡常数(K<sub>se</sub>)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、<sup>1</sup>HNMR谱进行了研究。讨论了协萃机理及萃合物的可能结构。
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.
