Synthesis of amidoxime-functionalized Fe3O4@SiO2 core–shell magnetic microspheres for highly efficient sorption of U(VI)

Adsorption of Co(II) on Graphene Oxides from Aqueous Solution

“…However, the entropy changes compensate the enthalpy changes, resulting in a negative value of the Gibbs free energy change (ΔG 0 ) and a spontaneous process at the conditions applied. The positive value of the entropy change (ΔS 0 ) may be attributed to the structure change of the composite complex [37,46]. As the temperature rises, Co(II) cations are more likely to be desolvated and the adsorption becomes more favorable.…”

Nanoparticles of zirconium hydrophosphate framed with a weakly-acidic cation-exchange polymer

“…In this case, constituents are synthesized simultaneously or inorganic particles are inserted into reaction media where polymerization of organics occurs. At last, the subclass (iii) is formed by magnetic nanoparticles: their core is a magnetic material coated with functionalized polymer (shell) [25][26][27][28]. Particles consisting of polymer core and inorganic shell are considerably larger: with size of several microns and more [29,30].…”

An Amidoximated-UHMEPE Fiber for Selective and High Efficient Removal of Uranyl and Thorium from Acid Aqueous Solution

“…From the point view of uranium resources and environmental protection [4] [5], separation and recovery of the essential uranium element in nuclear waste solution are also of great significance. Solid phase extraction [6] [7] (SPE) has been considered to be one of the most effective methods for recovery of materials because of its simplicity, low cost and wide adaptability [8].…”

“…UHM-WPE fiber alone does not have any capability to capture metal ion from aqueous solution, and functional ligands have to be anchored to the surface of UHMWPE fiber. Recently, numerous scientists have focused on sorbents combined with organic functional groups such as amino [9], polyhydroxyethylmethacrylate [10] [11], amidoxime (AO) [7] [12] [13], mercapto [14] etc. The sorbents with binding groups are promising candidates for sorption of actinides.…”

“…The sorbents with binding groups are promising candidates for sorption of actinides. Amidoxime groups have high selectivity and capacity for sorption of uranium ions in aqueous solution with η 2 -binding mode [7] [12] [13].…”
