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

The use of polyethyleneglycolmethacrylate-co-vinylimidazole (PEGMA-co-VI) microspheres for the removal of nickel(II) and chromium(VI) ions

“…Heavy metal contamination therefore is a very great environmental concern since it is very well known that the heavy metal ions such as cadmium, chromium, copper, lead, mercury, nickel, selenium, silver, and zinc are generally toxic in nature. Thus, heavy metal removal is a recent research area attracting a great interest [1][2][3][4]. Various removal methods such as membrane processes (dialysis, electrodialysis, reverse osmosis, etc.…”

Synthesis and characterization of hydrophilic and spherical poly(glycerol dimethacrylate-co-glycerol-1,3-diglycerolate diacrylate) microbeads

“…250 and 500 rpm). As explained in the related literature for different suspension polymerization systems [21,34,35], the average size reduced with increasing stir- Figure 3. ESRs of poly(GDMA-GDGDA) gel beads synthesized with different GDMA/GDGDA volume ratios at different pHs.…”

Solid Phase Extraction of Trace Al(III), Fe(II), Co(II), Cu(II), Cd(II) and Pb(II) Ions in Beverages on Functionalized Polymer Microspheres Prior to Flame Atomic Absorption Spectrometric Determinations

“…Among them, the crosslinked porous microspheres are mainly preferred due to their high surface areas, porosity, ease of preparation with desired size, durability, superior mobility and easy recovery from dispersion. 12,24,[27][28][29][30][31][32][33] Glycidyl methacrylate (GMA), a commercial industrial monomer possessing an epoxide ring in the side chain, is more appropriate for the preparation of functionalized porous microspheres with desired particle and pore size, and also their surfaces are easily modified via ring opening reaction of these glycidyl groups with various types of ligands. heterocyclic compounds containing nitrogen (N) and sulfur (S) donor atoms, have been found to be one of the efficient polydentate ligands used in the functionalization of polymeric supports.…”
