Recovering uranium from seawater has been the subject of many studies for decades, and has recently seen significant progress in materials development since the U.S. Department of Energy (DOE) has become involved. With DOE direction, the uranium upta

Capillary flow porometry (CFP) is an emerging technique to measure the most constricted part of the through pores in membranes. In our previous work, the technique was successfully tested for track-etch membranes, which are model membranes with strai

Uranium adsorbed on amidoxime-based polyethylene fibers in simulated seawater can be quantitatively eluted using 3 M KHCO3 at 40 °C. Thermodynamic calculations are in agreement with the experimental observation that at high bicarbonate concentration
