摘要：
Here we report a nanoadsorbent design, which integrates the high affinity of amidoxime (AO) groups and size effect of nanomaterials in nanofibrous composite mats prepared by a two-nozzle electrospinning process, for the adsorption of uraniumin simulated seawater with an uptake capacity of 1.6 mg U g(-1) adsorbent in the presence of massive amounts of interference ions.
