Item Electrochemical Synthesis and Characterization of a Schiff Base Ligand and Schiff Base-Nickel Complex(Addis Ababa Universty, 2008-07) Anbesu Bogale; Admassie Shimelis (PhD)The electropolymerizations of the Schiff base ligand and the Ni-Schiff base complex were carried out in aqueous H2SO4 solution. The film coated glassy carbon electrode showed an electrochemical response. The factors that affect the electroactivity of the film, such as number of cycles used for the film formation and pH were studied for both Schiff bases. The effect of sulphuric acid concentrations in which the Schiff base complex is dissolved was studied. Also, the stability of the polymer film in 1 M H2SO4, 1 M NaOH and methanol-water mixture (1:1) was investigated for the case of the Ni-metal Schiff base complex. The poly-film got the least stability in methanol-water (1:1) mixture. Keywords: Schiff bases, Schiff base- Ni metal complex, 6-(2-hydroxyphenylamino)-1,10-phenanthrolin-5-ol, Electropolymerization.
