| Abstract: | his paper has studied the effects which affect the batch extraction of Scandium with ELM. The prefered membrane system and the appropriate conditions have been determined.The paper has also studied the transfer process of Scandium through ELM, and established a reaction difussion model for type 2 facilitated transport, which has taken into account the aqueous diffusion, membrane diffusion and interfacial chemical reaction, as well as the ELM breakage.The derived equaition can qualitatively fit the experiment data on the extraction of Scandium. |
