Abstract
A separator for an electrochemical deionization cell for removing ions from a solution stream. The separator includes an anion exchange membrane layer formed from an anion exchange membrane material. The anion exchange membrane layer has a first surface and an opposing second surface. The separator further includes a porous layer adjacent to the anion exchange membrane layer and formed from a porous material. The porous layer has a first surface and an opposing second surface. The first surface of the porous layer is adjacent to the first surface of the anion exchange membrane layer.
Claims8
A separator for an electrochemical deionization cell for removing ions from a solution stream, the separator comprising:
- an anion exchange membrane layer formed from an anion exchange membrane material, the anion exchange membrane layer having a first surface and an opposing second surface;
- and
- a porous layer adjacent to the anion exchange membrane layer and formed from a porous material, the porous layer having a first surface and an opposing second surface, the first surface of the porous layer being adjacent to the first surface of the anion exchange membrane layer, the porous layer being at least partially filled with an ionic liquid, and the ionic liquid includes one or more cations including ammonium, (methyl)imidazolium, (methyl)pyrrolidinium, or a combination thereof.
