Selective recovery of mercury by Procion Brown MX 5BR immobilized poly(hydroxyethylmethacrylate/chitosan) composite membranes
(Elsevier Science Bv, 2002)
Metal chelating membranes have advantages as adsorbents in comparison to conventional microspheres or beads because they are not compressible and they considerably eliminate internal diffusion limitations. The aim of this ...
Reversible immobilization of urease onto Procion Brown MX-5BR-Ni(II) attached polyamide hollow-fibre membranes
(Elsevier Sci Ltd, 2002)
Urease was immobilized onto Procion Brown MX-5BR attached and Ni(II) incorporated microporous polyarnide hollow-fibre membrane via adsorption. Urease immobilization onto the polyamide hollow-fibre membrane from aqueous ...
Poly(hydroxyethyl methacrylate) membranes: As a hydrogel support for use in immobilized metal affinity chromatography
(Wiley-V C H Verlag Gmbh, 2003)
Lysozyme adsorption onto a dye ligand (Procion Red HE-3B) immobilized and Cu(II) incorporated poly(2-hydroxyethylmethacrylate) (pHEMA) membrane were investigated. The membranes were prepared by UV initiated photopolymerization ...
Immobilization of urease via adsorption onto L-histidine-Ni(II) complexed poly(HEMA-MAH) microspheres: Preparation and characterization
(Elsevier Sci Ltd, 2005)
Poly(2-hydroxyethyl methacrylate-co-N-methacryloly-L-histidinemethylester) poly(HEMA-MAH) microspheres was prepared via suspension polymerization. L-Histidine groups of the poly(HEMA-MAH) microspheres were then chelated ...
Equilibrium and kinetic studies on biosorption of Hg(II), Cd(II) and Pb(II) ions onto microalgae Chlamydomonas reinhardtii
(Academic Press Ltd- Elsevier Science Ltd, 2005)
The microalgae Chlamydomonas reinhardtii was used for the biosorption of Hg(II), Cd(II) and Pb(II) ions. The maximum adsorption of Hg(II) and Cd(II) ions on Chlamydomonas reinhardtii biomass was observed at pH 6.0 and the ...
Characterization of polyethylenimine grafted and Cibacron Blue F3GA immobilized poly (hydroxyethylmethacrylate-co-glycydylmethacrylate) membranes and application to bilirubin removal from human serum
(Elsevier Science Bv, 2005)
In this study, acrylic hydrogel copolymer membrane was synthesized from 2-hydroxyethylmethacrylate (HEMA) and glycidyl methacrylate (GMA) monomers. The pol ethylenimine polymer was then grafted onto membrane surface ...
Utilisation of native, heat and acid-treated microalgae Chlamydomonas reinhardtii preparations for biosorption of Cr(VI) ions
(Elsevier Sci Ltd, 2005)
The hexavalent chromium biosorption onto native, heat- and acid-treated Chlamydomonas reinhardtii was studied from aqueous solutions. Biosorption equilibrium was established in about 120 min. The surface properties of the ...
Cr(VI) biosorption from aqueous solutions using free and immobilized biomass of Lentinus sajor-caju: preparation and kinetic characterization
(Elsevier Science Bv, 2005)
The potential use of the free and immobilized mycelia (in carboxymethylcellulose (CMC)) of Lentinus sajor-caju to remove hexavalent form of chromium ions, Cr(VI), from aqueous solutions was evaluated using CMC bead as a ...
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 ...
Modification of surface properties of Lentinus sajor-caju mycelia by physical and chemical methods: evaluation of their Cr6+ removal efficiencies from aqueous medium
(Elsevier, 2005)
The hexavalent chromium biosorption onto untreated and heat-, acid- and alkali-treated Lentinus sajor-caju mycelia. were studied from aqueous solutions. The particles sizes of the fungal mycelia ranged from 100 to 200 mu ...
