Adsorption of chromium(VI) metal ions from aqueous solution using hexagonal ZnO particles: Equilibrium, kinetic and thermodynamic modelling studies
(Wiley, 2014)
Zinc oxide powders having hexagonal plate particles were prepared by homogeneous precipitation from boiling aqueous solutions that contained excess urea and 0.075 (Z075) and 0.300 (Z300) M Zn2+. The equilibrium, kinetic ...
Investigation on selective adsorption of Hg(II) ions using 4-vinyl pyridine grafted poly(ethylene terephthalate) fiber
(Wiley, 2012)
In the work, poly(ethylene terephthalate) (PET) fibers were grafted with 4-vinyl pyridine (4-VP) monomer using benzoyl peroxide (Bz(2)O(2)) as initiator in aqueous media. The removal of Hg(II) ions from aqueous solution ...
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 ...
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 ...
Adsorption behavior of congo red from an aqueous solution on 4-vinyl pyridine grafted poly(ethylene terephthalate) fibers
(John Wiley & Sons Inc, 2008)
In this study, a reactive fibrous adsorbent was prepared through the grafting of 4-vinyl pyridine monomer onto poly(ethylene terephthalate) (PET) fibers for the removal of Congo red (CR) dye from an aqueous solution with ...
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 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 ...
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 ...
Therapeutic affinity adsorption of iron(III) with dye- and ferritin-immobilized pHEMA adsorbent
(John Wiley & Sons Inc, 2001)
Microporous poly(2-hydroxyethylmethacrylate) (pHEMA) films carrying cibacron blue F3GA, Congo red, and ferritin were prepared and used for iron(III) removal from human plasma. pHEMA films were produced by a photopolymerization ...
Procion Green H-E4BD-immobilized porous poly(hydroxyethylmethacrylate) ion-exchange membrane: preparation and application to lysozyme adsorption
(Elsevier Science Bv, 2001)
Lysozyme adsorption onto Procion Green HE-4BD-immobilized poly(2-hydroxyethylmethacrylate) (pHEMA) membrane were investigated. The membrane were prepared by ultraviolet-initiated photopolymerization of HEMA in the presence ...
