Ca-alginate as a support for Pb(II) and Zn(II) biosorption with immobilized Phanerochaete chrysosporium
(Elsevier Sci Ltd, 2003)
The basidio spores of Phanerochaete chryosporium were immobilized in alginate gel beads, and the immobilized spore containing alginate beads were incubated for the growth of fungus. The biosorption of Pb2+ and Zn2+ ions ...
Procion Green H-4G immobilized poly(hydroxyethylmethacrylate/chitosan) composite membranes for heavy metal removal
(Elsevier Science Bv, 2003)
The effective removal of toxic heavy metals from environmental samples still remains a major topic of present research. Metal-chelating membranes are very promising materials as adsorbents when compared with conventional ...
Preparation and application of spacer-arm-attached poly (hydroxyethyl methacrylate-co-glycidyl methacrylate) films for urease immobilisation
(Elsevier Science Bv, 2003)
Immobilisation of urease onto plain and six-carbon spacer-arm (i.e. 1,6-diaminohexane) attached poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) [poly (HEMA-GMA)] films was studied. The epoxy groups containing ...
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 ...
