Electrochemical study of the interaction of nicotinamide with tryptophan in the presence and absence of nickel(II)
The interaction of nicotinamide with tryptophan in the presence and absence of nickel(II) in 0.1 M ammonium tartrate (pH 8.94) has been examined by voltammetric techniques. Tryptophan gave a catalytic hydrogen peak at -1.12 ... -
Structural features of a new [Fe(nicotinamide)(2)(H2O)(4)]center dot[Fe(H2O)(6)]center dot (SO4)(2)center dot 2H(2)O complex
A new nicotinamide complex of Fe(H) cation was prepared by reaction between ferrous sulfate and nicotinamide in aqueous solution. The complex was characterized on the basis of elemental analysis, FT IR and UV-VIS spectroscopy, ... -
Synthesis, spectroscopic and thermal studies of the copper(II) aspartame chloride complex
Cakir, S; Coskun, E; Naumov, P; Bicer, E; Bulut, I; Icbudak, H; Cakir, O (Elsevier Science Bv, 2002)Aspartame adduct of copper(II) chloride Cu(Asp)(2)Cl-2-2H(2)O (Asp= aspartame) is synthesized and characterized by elemental analysis, FT IR, UV/vis, ESR spectroscopies, TG, DTG, DTA measurements and molecular mechanics ... -
Voltammetric and polarographic studies of eriochrome Black T-nickel(II) complex
Cakir, O; Coskun, E; Bicer, E; Cakir, S (Scientific Technical Research Council Turkey-Tubitak, 2001)The electrochemical behaviour of complexes of Eriochrome Black T (EBT) with Ni(II) was studied, It was observed that EBT forms 1:1 and 1:2 complexes with Ni(II) in 0.1 M phosphate buffer at pH 6.0 by using Square-wave ... -
Voltammetric and spectroscopic behaviour of the copper adducts of thiol and thioether ligands under aerobic and anaerobic conditions
Joint spectroscopic (ESR, electronic absorption and FT IR) and voltammetric (square-wave and cyclic voltammetry) techniques were employed to investigate the properties of copper adducts with cysteine, N-acetylcysteine and ...
