Abstract
The disclosure relates to membranes and membranes systems for the separation of trace components in a fluid mixture.
Claims20
A process for the selective capture and/or removal of targeted contaminants from a source of fluid, comprising:
- filtering the source of fluid through a membrane to remove targeted contaminants,
- wherein the membrane comprises embedded adsorbents or adsorption sites that exhibit a high selectivity and capacity for the targeted contaminants, and
- wherein the source fluid, once flowed through the membrane, no longer comprises the targeted contaminants to any appreciable sense.
The process of claim 7, wherein the one or more types of metal ions are ions of mercury, arsenic, lead, chromium, cadmium, zinc, uranium, copper, iron, cobalt, silver, manganese, molybdenum, boron, calcium, antimony, or nickel.
The process of claim 7, wherein the metal ions are ions of mercury, arsenic, lead, chromium, or cadmium.
An ion-capture electrodialysis process for the selective capture and/or removal of a targeted ion from a feed source of fluid, comprising:
- applying an electric potential to the feed source of fluid, wherein ions in the feed source of fluid are drawn through an ion exchange membrane to an electrode of opposing charge,
- wherein after the electric potential is applied, the feed source of fluid is substantially depleted of ions that were drawn to the electrode;
- wherein the ion exchange membrane comprises embedded adsorbents or adsorption sites that exhibit a high selectivity and capacity for the targeted ion, and
- wherein the ion exchange membrane adsorbs the targeted ion once the electric potential is applied.
