DESCRIPTION:Presenter: Hannah Johnson\n\nGroup: Moreau\n\nTitle: Optimizing Metal-Organic Framework Adsorbents for the Recovery of Uranium from Seawater\n\nAbstract: Nuclear power, fueled by uraniumoxide, is an increasingly significant source of global energy due to its low carbon emissions and high efficiency. However, the current mineable supply of uranium is being depleted at a rate of 1% every year, and new sources and methods of uranium recovery will be required to sustain nuclear power as a viable energy source. The world ocean contains one thousand times more uranium  than  is  available  in  terrestrial  deposits  at  a  very  dilute  level  of  3.3ppb,  and  an  extraction technology that is selective and efficient at such low concentrations could potentially sustain the global uranium  demand  indefinitely. Solid  adsorbents,  specifically  metal-organic  frameworks  (MOFs),  are  one class of material that has shown great promise for oceanic uranium extraction, but further optimization is required  prior  to  large-scale  applications,  namely  with  regards  to  the  maximum  uranium  uptake capacity  and  the  adsorption  kinetics.  Recent  studies  have  demonstrated  two  effective  strategies, functionalization  and  defect  induction,  that  drastically  improve  the  performance  of  MOFs  as  uranium adsorbents by different mechanisms. Both alteration methods, as applied to a representative MOF species UiO-66, are discussed and compared, and some final considerations of this technology’s practicality and applicability are presented.\n\nZoom Information:\n\nImportant Note: Both internal and external WSU meeting attendees must be signed into Zoom to join the meeting.\n\nPlease refer to this guide on Joining WSU Zoom Meetings before trying to join the meeting:\n\nhttps://confluence.esg.wsu.edu/display/KB/Zoom+-+Joining+Meetings+and+Best+Practices\n\nJoin from PC, Mac, Linux, iOS, or Android: https://wsu.zoom.us/j/93950840487?pwd=UFZwRnlKK09JOXFGdjFaWEhaNHFOdz09\n\nMeeting ID: 939 5084 0487\n\nPasscode: 418252\n\nDate & Time: Apr 30, 2021 03:00 PM Pacific Time (US and Canada)
