乳状液型液膜法是一种先进的萃取技术 ,它比单纯的溶剂萃取法效率更高。本文以硫脲—TOA—煤油膜体系萃取金为例建立数学模型 ,通过对模型的分析 ,发现该萃取过程存在耗散结构。并从理论上推断出提高萃取效率的进出物料的极限比 ,对实际生产具有十分重要的意义。
Emulsion liquid membrane method is an advanced extraction technology, which is more efficient than simple solvent extraction. In this paper, thiourea-TOA-kerosene membrane extraction gold system as an example to establish a mathematical model, through the analysis of the model and found that the extraction process there is a dissipative structure. And theoretically inferred to increase the extraction efficiency of the material than the limit of the actual production is of great significance.
