Reversible immobilization of glucose oxidase on polyaniline grafted polyacrylonitrile conductive composite membrane
(Elsevier Sci Ltd, 2010)
Polyacrylonitrile membrane surfaces were modified with chemical polymerization of conductive polyaniline. The effect of aniline concentration on the grafting efficiency was investigated As the amount of grafted PANI increased ...
Biosorption of Reactive Blue 4 dye by native and treated fungus Phanerocheate chrysosporium: Batch and continuous flow system studies
(Elsevier, 2006)
The native and treated fungal biomass of Phanerocheate chrysosporium was used for the biosorption of a textile dye (i.e., Reactive Blue 4). In the batch system, the biosorption equilibrium time was about 4 h and the maximum ...
Effect of spacer-arm and Cu(II) ions on performance of L-histidine immobilized on poly(GMA/MMA) beads as an affinity ligand for separation and purification of IgG
(Elsevier, 2006)
In this study, the beads were prepared from glycidiyl methacrylate (GMA) and methyl methacrylate (MMA) via suspension polymerization and, the used beads fractions were between 75 and 150 mu m. The epoxy groups of the beads ...
Biosorption of benzidine based textile dyes "Direct Blue 1 and Direct Red 128" using native and heat-treated biomass of Trametes versicolor
(Elsevier, 2007)
The capacities and mechanisms of native and heat-treated white rot fungus "Trametes versicolor" biomass in removing of two different benzidine based dyes (i.e., Direct Blue 1, DB-1 and Direct Red 128, DR-128) from aqueous ...
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 ...
Single-step purification of recombinant Thermus aquaticus DNA polymerase using DNA-aptamer immobilized novel affinity magnetic beads
(Wiley, 2007)
A DNA aptamer specific for Thermus aquaticus DNA polymerase (Taq-polymerase) was immobilized on magnetic beads, which were prepared in the presented study. The effect of various parameters including pH, temperaturem and ...
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 ...
Immobilization of beta-galactosidase onto magnetic poly(GMA-MMA) beads for hydrolysis of lactose in bed reactor
(Elsevier, 2007)
In the present study, novel magnetic beads were prepared from glycidylmethacrylate and methylmethacrylate via suspension polymerization in the presence of a cross-linker (i.e. ethylenedimethylmethacrylate). The magnetic ...
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 ...
Studies on accumulation of uranium by fungus Lentinus sajor-caju
(Elsevier, 2006)
The untreated, heat- and alkali-treated Lentinus sajor-caju mycelia were used for the recovery of uranium from aqueous solutions. The effect of pH, temperature, initial concentration of UO22+, ions and contact time parameters ...
