对在氯仿溶液中用 1 -苯基 - 3 -甲基 - 4 - (α-呋喃甲酰基 )吡唑啉酮 - 5 (HPMαFP)对Co(Ⅱ )的萃取性能进行了研究。结果表明 ,HPMαFP的萃取效果随其浓度的增大而显著增加 ,还研究了HPMαFP与 1 ,1 0 -邻菲罗啉 (Phen)、三辛基氧膦(TOPO)、二苯亚砜 (DPSO)、2 ,2′ -联吡淀 (DIPY)的氯仿溶液对Co(Ⅱ )的协同萃取 ,结果是HPMαFP与Phen的协萃作用显著 ,与DIPY协萃作用较小 ,与TOPO、DPSO无协萃效应 ;还根据模拟萃合物Co(PMαFP) 2 和Co(PMαFP) 2 ·Phen的红外光谱和元素分析结果 ,讨论了萃合物的结构
The extraction of Co (Ⅱ) with 1 - phenyl - 3 - methyl - 4 - (α - furoyl) pyrazolone - 5 (HPMαFP) in chloroform solution was studied. The results showed that the extraction efficiency of HPMαFP significantly increased with the increase of its concentration. The effects of HPMαFP and 1,10-phenanthroline (Phen), trioctylphosphine oxide (TOPO), diphenyl sulfoxide (DPSO) ) And 2,2’-dipyridyl (DIPY) in chloroform. The results showed that the synergistic effect of HPMαFP and Phen was significant, the synergistic effect with DIPY was small, and there was no association with TOPO and DPSO The effect of extraction was also discussed. The structure of the complex was also discussed based on the infrared spectra and elemental analysis of the simulated complexes Co (PMαFP) 2 and Co (PMαFP) 2 · Phen
