Abstract
Described herein is an electrodialysis system, comprising a solid-state electrolyte configured to allow ions to flow from the one chamber through the solid-state electrolyte and into another chamber. Also described herein is a method of purifying an ion in a solution, the method comprising the steps of: providing a feed solution comprising an ion; contacting the feed solution with a solid-state electrolyte; applying a current to the solid-state electrolyte such that the ion passes through the solid-state electrolyte to create a recovery solution comprising the ion; and collecting the ion.
Claims20
An electrodialysis system, comprising:
- a first chamber comprising a first chamber input and a first chamber output;
- a first set of second and third chambers, wherein the second chamber comprises a second chamber input and a second chamber output, the third chamber comprises a third chamber input and a third chamber output, wherein the first chamber is electrically connected to an anode, and the third chamber is electrically connected to a cathode;
- a first semipermeable membrane positioned between the first and second chambers and configured to allow ions to flow from the second chamber through the first semipermeable membrane and into the first chamber;
- a solid-state electrolyte positioned between the second and third chambers and configured to allow ions to flow from the second chamber through the solid-state electrolyte and into the third chamber;
- a feed channel having a feed channel inlet and a feed channel outlet, wherein the feed channel outlet is fluidly connected to the second chamber input and wherein the feed channel inlet is fluidly connected to the second chamber output;
- a recovery channel having a recovery channel inlet and a recovery channel outlet, wherein the recovery channel outlet is fluidly connected to the first chamber input and the third chamber input and wherein the recovery channel inlet is fluidly connected to the first chamber output and the third chamber output;
- and
- a sample port fluidly connected to the recovery channel.
A method of purifying an ion in a solution, the method comprising the steps of:
- providing a feed solution comprising an ion;
- contacting the feed solution with a solid-state electrolyte;
- applying a current to the solid-state electrolyte such that the ion passes through the solid-state electrolyte to create a recovery solution comprising the ion;
- and
- collecting the ion.
