| 摘 要： | 本文系统进行了ＮａＯＨ溶液对负载苯酚的ＴＢＰ＋煤油溶剂的反萃取平衡实验。考虑苯酚的支萃取平衡和解离平衡，建立了反萃取的计算模式，并证明了模型的可行性。本文还讨论了ＮａＯＨ溶液浓度，油水相比，萃取平衡分配系数，溶剂中的负载苯酚浓度和ＮａＯＨ溶液中初始酚含量对反萃取率的影响。

| Abstract: | In this paper, a series of equilibrium experiments have been carried out for stripping of solvent by NaOH aqueous solution containing different concentration of phenol. On the base of stripping equilibrium and dissociation equilibrium of phenol, a model of stripping efficiency has been proposed. The calculated results of stripping efficiency have been showed that the model precision was satisfied. The effects of NaOH concentration, ratio of organic phase to aqueous phase R, extraction distribution ratio D', phenol concentration loaded by solvent (A) and initial phenol concentration in NaOH aqueous solution (B) on stripping efficiency Y have been investigated. |
