Effect of the nature of the crosslinking agent on the metal-ion complexation characteristics of 4 mol % DVB- and NNMBA-crosslinked polyacrylamide-supported glycines

Preparation and characterization of polyethyleneglycolmethacrylate (PEGMA)-co-vinylimidazole (VI) microspheres to use in heavy metal removal

“…Some of the similar investigations related with this study are summarized as follows. George et al investigated the adsorptions of Co(II), Ni(II), Cu(II) and Zn(II) ions onto the N,N -methylenebisacrylamide cross-linked polyacrylamide and glycine attached divinylbenzene structures, and they reported that the maximum Cu(II) ion adsorption could be achieved at 2.5 h [19]. Shreedhara-Murthy and Ryan investigated uranium, mercury, copper, cadmium and lead ions adsorption onto the cellulose dithiocarbamate resin and they reported that the maximum adsorption value could be achieved in a very long time [20].…”

Poly(ethylene glycol dimethacrylate-n-vinyl imidazole) beads for heavy metal removal

“…Among these techniques, adsorption is generally preferred for the removal of heavy metal ions due to its high efficiency, easy handling, availability of different adsorbents and cost effectiveness. Toxic metal ion removal by using chelating polymers would be of great importance in environmental applications [8][9][10][11][12][13][14][15][16][17][18]. Several criteria are important in the design of metal-chelating polymers with substantial stability for the selective removal of metal ions: specific and fast complexation of the metal ions as well as the reusability of the metal-chelating polymer.…”

In Separation and Purification

“…The metal -binding capabilities of poly(AAm) crosslinked with N,N -methylene -bis -acrylamide (NNMBA) immobilized with Gly was reported for heavy metals: Co 2+ , Cu 2+ , Fe 2+ , Fe 2+ , Ni 2+ , and Zn 2+ ions. The metal -binding capacity increased with the increase in crosslinking up to 8% beyond which it declined [230,231] .…”
