Biosorption of mercury(II), cadmium(II) and lead(II) ions from aqueous system by microalgae Chlamydomonas reinhardtii immobilized in alginate beads
Bayramoğlu, Gülay; Tüzün, İlhami; Çelik, Gökçe; Yilmaz, Meltem; Arica, M. Yakup (Elsevier, 2006)The potential use of the immobilized microalgae (in Ca-alginate) of Chlamydomonas reinhardtii to remove Hg(II), Cd(II) and Pb(II) ions from aqueous solutions was evaluated using bare Ca-alginate bead as a control system. ... -
Biosorption of Reactive Blue 4 dye by native and treated fungus Phanerocheate chrysosporium: Batch and continuous flow system studies
Bayramoğlu, Gülay; Çelik, Gökçe; Arıca, M. Yakup (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 ... -
Equilibrium and kinetic studies on biosorption of Hg(II), Cd(II) and Pb(II) ions onto microalgae Chlamydomonas reinhardtii
Tüzün, İlhami; Bayramoğlu, Gülay; Yalçın, Emine; Başaran, Gökben; Çelik, Gökçe; Arıca, M. Yakup (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 ... -
Immunoglobulin G adsorption behavior of L-histidine ligand attached and Lewis metal ions chelated affinity membranes
Bayramoğlu, Gülay; Çelik, Gökçe; Arica, M. Yakup (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 ... -
Modification of surface properties of Lentinus sajor-caju mycelia by physical and chemical methods: evaluation of their Cr6+ removal efficiencies from aqueous medium
Bayramoğlu, Gülay; Çelik, Gökçe; Yalçın, Emine; Yılmaz, Meltem; Arıca, M. Yakup (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 ... -
Preparation and characterization of sulfonyl-hydrazine attached poly(styrene-divinylbenzene) beads for separation of albumin
Bayramoğlu, Gülay; Şenkal, Filiz B.; Çelik, Gökçe; Arica, M. Yakup (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 ... -
Studies on accumulation of uranium by fungus Lentinus sajor-caju
Bayramoğlu, Gülay; Çelik, Gökçe; Arıca, M. Yakup (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 ...
