This Final Report for Project 14-6789: “Optimizing Polymer- Grafted Amidoxime-based Adsorbents for Uranium Uptake from Seawater” consists of three independent parts focused on (i) polymer design optimization, (ii) effect of environmental factors on uranium adsorption, and (iii) effect of flow rate on uranium uptake. The polymer design section focuses on the study of polymer graft-chain conformation through neutron reflectometry and the influence of conformation on adsorbent performance. The environmental effects section was divided into four subcategories: (1) investigating the impact of aqueous ions on uranium adsorption and the development of an object oriented modeling framework for analysis of aqueous adsorption modeling; (2) analyzing and predicting adsorption capacities as a function of temperature; (3) developing a multi-scale paradigm by coupling aqueous adsorption modeling with molecular level models to predict competitive adsorption between vanadium and uranium at various pH values; (4) investigating the effect of competing adsorbates on uranium adsorption capacity and the possibility of uranium recovery from desalination brine reject. The final section is concerned with determining the effect of current velocity on uranium uptake by developing an understanding of the relationship between mass transfer kinetics and flow rate.
