Preparation of chelating membranes to remove metal cations from aqueous solutions

Adsorption characteristics of Ni(II) onto MA–DTPA/PVDF chelating membrane

“…Due to the stability of metal complexes, the recovery of nickel from metal plating faces challenges. Membrane techniques, especially the chelating membrane, have found applications in the heavy metal polluted wastewater [6,17]. Also, there are strong complexing agents including ethylenediamine tetra-acetic acid (EDTA) and diethylenetriaminepentaacetic acid (DTPA), which are adopted to functionalize the polymeric materials for heavy metal recovery [18][19][20][21].…”

Self-assembled CeO2 on carbon nanotubes supported Au nanoclusters as superior electrocatalysts for glycerol oxidation reaction of fuel cells

“…The strong electrostatic force between COO -functional group of PC and Ce 3+ and coordination bonding between COO -and CeO2 NPs could immobilize and stabilize Ce 3+ and CeO2 NPs, thus preventing the aggregation of the formed CeO2 NPs [47,48]. This result further shows that the 1-PC functionalization of MWNT is beneficial for self-assembly and uniform dispersion of CeO2 NPs.…”

Preparation and adsorption performance of a novel bipolar PS-EDTA resin in aqueous phase

“…During the past decade, several metal-retaining resin, containing a variety of complexion or chelating ligands, have been reported to efficiently remove heavy metals [20][21][22][23]. Synthetic polymers containing amino, thio, oxo, carboxyl, phosphoryl, and so on have been developed.…”
