Adsorption of heavy metal ions onto ethylene diamine-derived and Cibacron Blue F3GA-incorporated microporous poly(2-hydroxyethyl methacrylate) membranes
Denizli, A; Say, R; Patir, S; Arica, MY (Elsevier Science Bv, 2000)Microporous poly( 2-hydroxyethylmethacrylate) (PHEMA) membranes carrying ethylene diamine (EDA) and Cibacron Blue F3GA were prepared for the removal of heavy metal ions (i.e. mercury, copper, lead and cadmium) from aqueous ... -
Affinity separation of plasma proteins using a newly synthesized methacrylamidoalanine incorporated porous pHEMA membranes
Yavuz, H; Patir, S; Say, R; Arica, Y; Denizli, A (Marcel Dekker Inc, 2002)In this study, we synthesized a novel adsorbent to obtain high protein-adsorption capacity utilizing 2-methacrylamidoalanine (MAAL) containing membrane. Amino acid-ligand MAAL was synthesized by using methacrylochloride ... -
Biosorption of cadmium(II), lead(II) and copper(II) with the filamentous fungus Phanerochaete chrysosporium
Say, R; Denizli, A; Arica, MY (Elsevier Sci Ltd, 2001)The biosorption from artificial wastewaters of heavy metals (Cd(II), Pb(II) and Cu(II)) onto the dry fungal biomass of Phanerochaete chryosporium was studied in the concentration range of 5-500 mg 1(-1). The maximum ... -
Biosorption of inorganic mercury and alkylmercury species on to Phanerochaete chrysosporium mycelium
Saglam, N; Say, R; Denizli, A; Patir, S; Arica, MY (Elsevier Sci Ltd, 1999)The biosorption of inorganic mercury (HgCl2), methyl mercury (CH3HgCl) and ethyl mercury (C2H5HgCl) onto the dry biomass of Phanerochaete chryosponum was studied from aqueous media which concentrations in the range of 5-500 ... -
Comparison of adsorption performances of metal-chelated polyamide hollow fibre membranes in lysozyme separation
Senel, S; Kassab, A; Arica, Y; Say, R; Denizli, A (Elsevier Science Bv, 2002)Commercially available microporous polyamide hollow fibres are modified by acid hydrolysis to activate the reactive groups and subsequently binding of the ligand, i.e. Cibacron Blue F3GA. Then the Cibacron Blue F3GA-derived ... -
Dye affinity poly(2-hydroxyethyl methacrylate) membranes for removal of heavy metal ions
Denizli, A; Say, R; Arica, MY (Marcel Dekker Inc, 2000)The dichlorotriazinyl dye-ligand Procion Red HE-3B-anchored poly(EGDMA-HEMA) membranes were used for removal of heavy metal ions (i.e., copper, arsenic, cadmium and mercury) from aqueous media containing different amounts ... -
