| 摘 要： | 以醋酸稀溶液为萃取对象，进行萃取特性和机理的研究．讨论了醋酸溶液初始浓度、磷酸三丁酯(TBP)在有机相中的浓度及温度对络合萃取相平衡分配系数的影响；采用对应溶液法求得了TBP萃取稀醋酸的分配平衡常数为0．05，说明萃取过程是以化学络合萃取为主，而物理萃取可忽略；通过斜率法确定TBP萃取醋酸的萃合比为1，并利用红外光谱法加以证实；同时结合测定有机相中水的含量进一步确定萃合物的结构式．

| Abstract: | In this paper, the effects of the initial concentration of acetic acid , TBP concentration and the temperature on the distribution coefficient of extraction equilibrium were systematically investigated. By adopting corresponding solution method the distribution constant (=0.05) was obtained. The structure and mechanism of the extraction in the organic solvent loaded with acetic acid were studied by IR spectrometer. |
