Extracting a target ion from an aqueous solution by ion exchange and electropotential ion transport |
摘要 |
Processes and apparatuses for separating ions from an aqueous solution are provided which utilize a first separation by an ion exchange medium in combination with second separation by a D.C. electropotential gradient. The first separation separates the target ion by ion exchange and the second separation effects migration of the ions from the ion exchange medium, through a ion permeable, hydrophobic membrane into a second zone, which may contain a buffer. The hydrophobic membrane substantially resists fouling.
