本文研究了1-苯基-3-甲基-4-苯甲酰基吡唑酮-5(PMBP,HA)及1,10-菲绕啉(B)从高氯酸及醋酸钠构成的缓冲溶液中(pH=4,μ=0.1),对全部希土离子(包括Y~(3+),不包括Pm~(3+))的协同萃取。此体系可表示为Ln~(3+)(10~(-4)M)/HClO_4,NaAc(μ=0.1)/PMBP-Phen-CHCl_3。用斜率法确定协萃合物组成为LnA_3B,并求出各希土离子的协萃平衡常数logK_(?)以logK_(?)对原子序数Z作图,表现出四分组效应。相邻希土之间以及轻重希土之间的分离系数比单独用PMBP萃取时来得大。此体系有希望用于轻重希土分离。此外,还用萃取法制得了固体协萃合物,并对其红外光谱进行了分析讨论。
In this paper, the buffer solution of 1-phenyl-3-methyl-4-benzoylpyrazolone-5 (PMBP, HA) and 1,10-phenanthroline (B) (PH = 4, μ = 0.1), all of the Greek ions (including Y ~ (3+), excluding Pm ~ (3+)) synergistic extraction. This system can be expressed as Ln ~ (3 +) (10 ~ (-4) M) / HClO_4, NaAc (μ = 0.1) / PMBP-Phen-CHCl_3. The composition of the complex was determined to be LnA_3B by the slope method, and the equilibrium constant of the scintillation counter ion, logK_ (?), Was plotted against logarithm Z with log K_ (?) To show the quadrant effect. The separation factor between adjacent relics and between light and heavy relics is greater than when extracted by PMBP alone. This system is hopeful for the separation of light and heavy. In addition, solid extraction compounds were also prepared by extraction method, and their infrared spectra were analyzed and discussed.
