Abstract
In general, the present invention is directed to a metal-organic framework (MOF) for use in removing liquid phase compounds, in particular anionic and cationic species, as well as a combination of anionic and cationic species, from a liquid or liquid stream. In addition, the present invention is directed to various methods or processes for utilizing the MOF to remove such compounds from a liquid or liquid stream, such as an industrial process stream, and for using the MOF at elevated temperatures.
Claims9
A method for removing a pre-determined species from a liquid, comprising:
- contacting a zirconium-based MOF with a liquid comprising a pre-determined species to be removed and having a temperature that is greater than approximately 45° C.;
- adsorbing the species onto the MOF.
A method for removing an oxy-anion from a liquid process stream used in a nuclear reactor system, comprising:
- contacting a zirconium-based MOF with a liquid process stream used in a nuclear reactor system comprising an oxy-anion to be removed and having a temperature that is greater than approximately 45° C.;
- adsorbing the species onto the MOF.
