Significantly Enhanced Uranium Extraction from Seawater with Mass Produced Fully Amidoximated Nanofiber Adsorbent
Abstract
The oceans contain hundreds of times more uranium than terrestrial ores. Fiber‐based adsorption is considered to be the most promising method to realize the industrialization of uranium extraction from seawater. In this work, a pre‐amidoximation with a blow spinning strategy is developed for mass production of poly(imide dioxime) nanofiber (PIDO NF) adsorbents with many chelating sites, excellent hydrophilicity, 3D porous architecture, and good mechanical properties. The structural evidences from 13 C NMR spectra confirm that the main functional group responsible for the uranyl binding is not “amidoxime” but cyclic “imidedioxime.” The uranium adsorption capacity of the PIDO NF adsorbent reaches 951 mg‐U per g‐Ads in uranium (8 ppm) spiked natural seawater. An average adsorption capacity of 8.7 mg‐U per g‐Ads is obtained after 56 d of exposure in natural seawater via a flow‐through column system. Moreover, up to 98.5% of the adsorbed uranium can be rapidly eluted out and the adsorbent can be regenerated and reused for over eight cycles of adsorption–desorption. This new blow spun PIDO nanofabric shows great potential as a new generation adsorbent for uranium extraction from seawater.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
