Mulazimoglu, Aysen Demir; Yilmaz, Ecir; Mercimek, Bedrettin; Mulazimoglu, Ibrahim Ender (Univ Tehran, Fac Chemistry, Center Excellence Electrochemistry, 2012)In the present work, electrochemical and spectroelectrochemical behaviors of 1-nitroso-2-naphthol has been studied by cyclic voltammetry and electrochemical impedance spectroscopy techniques in non-aqueous media. Cyclic ... -
Electrochemical Grafting by Reduction of 4-Methylaminobenzenediazonium Salt at GC, Au and Pt Electrode: Investigation of Sensitivity Against Phenol by Cyclic Voltammetry
Mulazimoglu, Aysen Demir; Mulazimoglu, Ibrahim Ender; Mercimek, Bedrettin (Univ Tehran, Fac Chemistry, Center Excellence Electrochemistry, 2012)The aim of this study is to modify a glassy cabon, gold and platinum electrode with 4-methylaminobenzenediazonium salt (MABDAS) to evaluate the possible application on the detection of phenol by cyclic voltammetry (CV). ... -
Selective extraction of iron(III) from aqueous nitrate solution in the presence of cobalt(II), copper(II) and nickel(II) ions using BiS(Delta(2)-2-imidazolinyl)-5,5 '-dioxime
Teke, Mustafa; Mercimek, Bedrettin; Özler, Mehmet Ali; Ayar, Ahmet (Japan Soc Analytical Chemistry, 2004)The feasibility of using bis(Delta(2)-2-imidazolinyl)-5,5'-dioxime (H2L) for the selective extraction of iron(III) from aqueous solutions was investigated by employing an solvent-extraction technique. The extraction of ... -
Synthesis and Characterization of Chitosan/TiO2 Composite Beads for Improving Stability of Porcine Pancreatic Lipase
Deveci, İlyas; Doğac, Yasemin İspirli; Teke, Mustafa; Mercimek, Bedrettin (Humana Press Inc, 2015)The purpose of the present work is improving stability properties of porcine pancreatic lipase (triacylglycerol lipase, E.C.3.1.1.3) by immobilization on chitosan/TiO2 composite beads. The immobilization parameters were ... -
Synthesis of a novel heterocyclic dioxime and its mononuclear complexes with Ni(II), Co(II), Cu(II), Zn(II), Cd(II) and Hg(II)
Mercimek, Bedrettin; Özler, Mehmet Ali; İrez, Gazi; Bekaroğlu, Özer (Marcel Dekker Inc, 1999)In this work, a novel heterocyclic dioxime (2,3-hydroximino-4-phenyl-6-phenlyazo-1-thia-4,5-diazacyclohexa-5-diene, H2L) was synthesized by reacting dithizone with cyanogen di-N-oxide. H2L forms mononuclear complexes ... -
TiO2 beads and TiO2-chitosan beads for urease immobilization
Doğaç, Yasemin İspirli; Deveci, İlyas; Teke, Mustafa; Mercimek, Bedrettin (Elsevier Science Bv, 2014)The aim of the present study is to synthesize TiO2 beads for urease immobilization. Two different strategies were used to immobilize the urease on TiO2 beads. In the first method (A), urease enzyme was immobilized onto ...
