1-苯基-3-甲基-4-三氟乙酰基吡唑酮-(5)与Nd(III),Eu(III),Yb(III)的萃取平衡及络合物的合成和性质
STUDIES ON EXTRACTION EQUILIBRIA OF Nd(III), Eu(III), Yb(III)WI TH 1-PHENYL-3-METHYL-4-TRIFLUOROACETYL-PYRAZOL-ONE-5(PMTFP), THE SYNTHESIS AND THE CHARACTERIZATION OF Nd(III), EU(III), Yb(III)CHELATES
【摘要】 在30℃及0.5mol·L(-1)NaNO6条件下,测定了Nd(III),Eu(III),Yb((III)与1-苯基-3-甲基-4-三氟乙酰基吡唑酮-(5)(PMTFP)氯仿溶液体系的萃取平衡常数及萃合物的组成。用萃取法合成了Nd(III),Eu(III),Yb(III)与PMTFP的固体络合物,分析了它的组成,并通过它们的红外光谱和紫外光谱,探讨了络合物的结构。
【Abstract】 The equilibrium constants of extraction of Ln(III)/0.5 mol·L-1 NaNO)3/PMTFP-CttCl3 (Ln=Nd, Eu, Yb) systems and the composition of the extractedmetal chelates have been determined. The solid chelates of Ln-PMTFP have beensynthesized by using extraction method, its compositions have been analyzed and itsstructures have been explored through infrared spectra and UV-spectra.
