Adsorption of Cr(VI) onto PEI immobilized acrylate-based magnetic beads: Isotherms, kinetics and thermodynamics study
(Elsevier Science Sa, 2008)
Magnetic poly(GMA-EGDMA) beads were prepared from glycidylmetharylate (GMA) and ethyleneglycol dimethacrylate (EGDMA) in the presence of Fe3O4 nano-powder via suspension polymerization. After polymerization, the magnetic ...
Preparation of nanofibrous polymer grafted magnetic poly(GMA-MMA)-g-MAA beads for immobilization of trypsin via adsorption
(Elsevier, 2008)
Poly (glycidylmethacrylate-methylmethacrylate), poly(GMA-MMA) beads were prepared via suspension polymerization in the presence of ferric ions. The epoxy groups of the poly(GMA-MMA) beads were converted into amino groups ...
Adsorption of trypsin onto magnetic ion-exchange beads of poly(glycidylmethacrylate-co-ethyleneglycoldimethacrylate)
(John Wiley & Sons Inc, 2008)
Magnetic beads were prepared from glycidyl methacrylate (GMA), and ethyleneglycol dimethylmethacrylate (EGDMA) in the presence of Fe3O4 nanopowder via suspension polymerization. The magnetic beads were characterized by ...
Removal of Cd(II), Hg(II), and MID ions from aqueous solution using p(HEMA/Chitosan) membranes
(Wiley, 2007)
An interpenetration network (IPN) was synthesized from 2-hydroxyethyl methacrylate (HEMA) and chitosan, p(HEMA/chitosan) via UV-initiated photo-polymerization. The selectivity to different heavy metal ions viz Cd(II), ...
Studies of adsorption of alkaline trypsin by poly(methacrylic acid) brushes on chitosan membranes
(John Wiley & Sons Inc, 2008)
Poly(methacrylic acid)-grafted chitosan membranes (chito an-g-poly(MAA)) were prepared in two sequential steps: in the first step, chitosan membranes were prepared by phase-inversion technique and then epichlorohydrin was ...
Preparation of methacrylamide grafted and dye-ligand immobilized PET fibers: Studies of adsorption and purification of lysozyme
(John Wiley & Sons Inc, 2008)
In this study, novel affinity chromatographic fibers was prepared from methacrylamide grafted poly(ethylene terephthalate), PET-g-pMAA, using benzoyl-peroxide as an initiator. A dye ligand (i.e., Procion Brown) as a ligand ...
Biosorption of mercury(II), cadmium(II) and lead(II) ions from aqueous system by microalgae Chlamydomonas reinhardtii immobilized in alginate beads
(Elsevier, 2006)
The potential use of the immobilized microalgae (in Ca-alginate) of Chlamydomonas reinhardtii to remove Hg(II), Cd(II) and Pb(II) ions from aqueous solutions was evaluated using bare Ca-alginate bead as a control system. ...
Immunoglobulin G adsorption behavior of L-histidine ligand attached and Lewis metal ions chelated affinity membranes
(Elsevier Science Bv, 2006)
Immobilized metal affinity membranes were prepared by chelating Cu(II) and Fe(III) ions on poly(2-hydroxyethyl methacrylate-glycidyl methacrylate), poly(HEMA-GMA) membranes using L-histidine as a chelating ligand. To achieve ...
Preparation and characterization of sulfonyl-hydrazine attached poly(styrene-divinylbenzene) beads for separation of albumin
(Elsevier Science Bv, 2007)
Novel sulfonyl-hydrazine carrying poly(styrene-divinylbenzene), poly(S-DVB)-S-NH2 ion-exchange beads (size between 210 and 425 mu m) were prepared via suspension polymerization and, were first used as an ion-exchange support ...
Purification of lysozyme from egg white by Reactive Blue 4 and Reactive Red 120 dye-ligands immobilised composite membranes
(Elsevier Sci Ltd, 2005)
A composite membrane was synthesized from 2-hydroxyethylmethacryl ate (HEMA) and chitosan (pHEMA/chitosan) via UV initiated photo-polymerisation. Reactive Blue 4 (Blue-4) and Reactive Red 120 (Red-120) were immobilised ...
