(E)-N′-Hydroxy-N,N-dimethyl-2-(3-nitrophenyl)acetimidamide

IUCrData, 2019
In the crystal of the title compound, C10H13N2O3, inversion dimers linked by pairs of N—H...O hydrogen bonds generate R22(6) loops. The dimers are linked by weak C—H...O and C—H...π interactions, resulting in a three-dimensional network.

Preparation of amidoxime-fiber adsorbents by radiation-induced grafting

, 1995
The fibrous adsorbents containing amidoxime groups were synthesized by radiation-induced graft polymerization of acrylonitrile onto polypropylene fibers, followed by functionalization of cyano groups to amidoxime groups with hydroxylamine.

High performance of amidoxime/amine functionalized polypropylene for uranyl (VI) from aqueous solution

e-Polymers, 2013
Amidoxime-based adsorbents are widely investigated as the main adsorbent in the recovery of uranium from seawater. However, the adsorption rate and loading capacity of such adsorbents should be further improved due to the economic viability consideration.
