Removal of chromium(VI) from aqueous solutions using poly(4-vinyl pyridine) beads
(Wiley, 2006)
Sorption of hexavalent chromium ions from aqueous solution by poly 4-vinyl pyridine [Poly(4-VP)] was studied. The batch method was applied for adsorption processes. The effects of initial ion concentration, time, pH and ...
Evaluation of lysozyme adsorptive behaviour of pHEMA-based affinity membranes related to the surface energy and its components to be used in chromatographic fields
(Elsevier, 2004)
We have studied the influence of the surface energy and its components of two different dye-ligand immobilised poly(hydroxyethylmethacrylate) (pHEMA) membranes to the adsorption of a protein "lysozyme" from aqueous solutions. ...
Poly(2-hydroxyethylmethacrylate)/chitosan dye and different metal-ion-immobilized interpenetrating network membranes: Preparation and application in metal affinity chromatography
(John Wiley & Sons Inc, 2003)
Composite membranes were synthesized with 2-hydroxyethylmethacrylate and chitosan (pHEMA/chitosan) via an ultraviolet-initiated photopolymerization technique in the presence of an initiator (alpha,alpha'-azobisisobutyronitrile). ...
Preparation of ion-exchange beads based on poly (methacrylic acid) brush grafted chitosan beads: Isolation of lysozyme from egg white in batch system
(Elsevier Science Bv, 2007)
Poly(methacrylic acid) brush grafted crosslinked-chitosan (chitosan-g-poly(MAA)) beads were prepared in two sequential steps: in the first step, chitosan beads were prepared by phase-inversion technique and then were ...
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 ...
DNA adsorption on a poly-L-lysine-immobilized poly(2-hydroxyethyl methacrylate) membrane
(Wiley, 2003)
The DNA adsorption properties of poly-L-lysine-immobilized poly(2-hydroxyethyl methacrylate) (pHEMA) membrane were investigated. The pHEMA membrane was prepared by UV-initiated photopolymerization and activated with ...
Kinetics of mercury ions removal from synthetic aqueous solutions using by novel magnetic p(GMA-MMA-EGDMA) beads
(Elsevier, 2007)
Poly(glycidylmethacrylate-methylmethacrylate), p(GMA-MMA-EGDMA), magnetic beads were prepared via suspension polymerization in the presence of ferric ions. The epoxy groups of the beads were converted into amino groups via ...
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 ...
Dye-ligand immobilized IPNs membrane for removal heavy metal ions
(Wiley-V C H Verlag Gmbh, 2003)
We have developed a novel approach to obtain high metal sorption capacity utilizing a membrane containing chitosan and an immobilized reactive dye (i.e. Reactive Yellow-2). The composite membrane was characterized by SEM, ...
Immobilization of catalase via adsorption onto L-histidine grafted functional pHEMA based membrane
(Elsevier Science Bv, 2001)
Poly(2-hydroxyethylmethacrylate) (pHEMA) based flat sheet membrane was prepared by UV-initiated photopolymerization technique. The membrane was then grafted with L-histidine. Catalase immobilization onto the membrane from ...
