Congo Red attached monosize poly(HEMA-co-MMA) microspheres for use in reversible enzyme immobilisation
Yavuz, H.; Bayramoğlu, G.; Kaçar, Y.; Denizli, A.; Arica, M.Y. (Elsevier Science Sa, 2002)Monosize and non-porous poly(2-hydroxyethylmethacrylate-co-methylmethacrylate) (poly(HEMA-co-MMA)), microspheres were prepared by dispersion polymerisation of HEMA and MMA in an ethanol-water medium in the presence of an ... -
Covalent immobilization of lipase onto hydrophobic group incorporated poly(2-hydroxyethyl methacrylate) based hydrophilic membrane matrix
Bayramoğlu, G.; Kacar, Y.; Denizli, A.; Arica, M.Y. (Elsevier Sci Ltd, 2002)In this study, a hydrophobic group containing monomer, 2-methacrylamidophenyalanine (MAPA) was prepared by using methacrylochloride and phenylalanine. Then, poly(2-hydroxyethyl methacrylate-co-methacrylamido-phenlyalanine) ... -
Dye-ligand immobilized IPNs membrane for removal heavy metal ions
Bayramoğlu, G.; Yalçın, E.; Genç, O.; Arica, M.Y. (Wiley-V C H Verlag Gmbh, 2003)We have developed a novel approach to obtain high metal sorption capacity utilizing a membrane containing chitosan and an immobilized reactive dye (i.e. Reactive Yellow-2). The composite membrane was characterized by SEM, ... -
Entrapment of Lentinus sajor-caju into Ca-alginate gel beads for removal of Cd(II) ions from aqueous solution: preparation and biosorption kinetics analysis
Bayramoğlu, G.; Denizli, A.; Bektaş, S.; Arıca, M.Y. (Elsevier Science Bv, 2002)A white rot fungus species Lentinus sajor-caju biomass was entrapped into alginate gel via a liquid curing method in the presence of Ca(II) ions.
