Preparation of a Porous Silica-Based Composite Resin Functionalized with Amidoxime Groups for Simultaneous Uranium and Vanadium Extraction from Simulated Seawater

Metals
The sustainable development of nuclear energy requires a secure long-term uranium supply. Seawater uranium extraction offers a nearly inexhaustible resource; however, its commercialization is limited due to high costs. To improve economic viability, this

Amidoximes: promising candidates for CO2 capture

Energy & Environmental Science, 2011
Monoethanolamine (MEA) dominates power plant carbon dioxide (CO2) scrubbing processes, though with major disadvantages such as a 8–35% energy penalty. Here we report that structurally comparable amidoximes are promising CO2 capture agents based on RIMP2 electronic structure calculations.

Origin of the unusually strong and selective binding of vanadium by polyamidoximes in seawater

Nature Communications, 2017
Amidoxime-functionalized polymeric adsorbents are the most promising materials for harvesting uranium from seawater. Here the authors investigate the preferential extraction of vanadium over uranium by polyamidoximes by exploring the unusually strong and

Synthesis and extraction properties of 1,2-bis(amidoxime) derivatives

, 2002
Four 1,2-bis(amidoxime)s bearing benzoate groups were synthesized. Their complexing properties were studied by the liquid-liquid extraction of selected alkali (Na+ and K+) and transition metals (Hg2+, Cu2+, Pb2+ and Ni2+).
