Diffusional Separation in Ternary Systems

这项提议将研究设计一种新的分离过程的可能性，以使两种物质(在溶液中)彼此分离。这种分离的可能性取决于两个组分在一种称为亚稳区的特殊热力学状态下的扩散性质。需要资金来测量和研究这些扩散特性，并对分离成分的可能性进行探索性的理论和实验研究。像这里选择研究的这样的分离问题非常常见，在各种各样的实际情况中经常遇到，包括从溶液中回收高价值金属、蒸馏、生物产品的纯化以及从液体中去除有毒金属离子。设计新的分离技术来处理这种情况将对处理操作的效率和可能的经济性产生重大影响。

This proposal will investigate the possibility of devising a novel separation process for separating two materials (in a solution) from each other. The possibility of such separation depends on the diffusion properties of the two components in a special thermodynamic state known as metastable region. Funds are requested for measuring and studying these diffusion properties and for conducting exploratory theoretical and experimental studies on the possibility of separating the components. Separation problems such as the one chosen here for study are very common and are frequently encountered in a wide variety of practical situations including recovery of high-value metals from solution, distillation, purification of biological products, and removal of toxic metal ions from liquids. Devising novel separation techniques to deal with such situations will have a significant impact on the efficiency and, possibly, the economics of processing operations.
