|Title:||Preparation And Characterization Of The Cobaloxime Complex And Its Use In Fabrication Of A Modified Electrode. An Electrochemical Experiment For Undergraduate Course [preparação E Caracterização Do Complexo Cobaloxima E Sua Utilização Na Construção De Um Eletrodo Modificado. Um Experimento Eletroquímico No Curso De Graduação]|
|Abstract:||The present experiment describes the preparation, characterization of n-butyl(pyridil)cobaloxime complex and its electrochemical property. The infrared and uv-visible absorption spectra were used to characterize the complex obtained. The infrared spectrum of the compound showed characteristics bands that indicated the formation of the Co-C chemical bond formation. The electronic absorption spectrum in acetonitrile showed transition bands attributed to π-π*, metal-to-ligand charge transfer, d-d transitions and charge transfer Co-C. The electrochemical property was investigated by the pulse differential voltammetry technique. Two oxidation processes: Co(I)/Co(II) at -423 mV and Co(II)/Co(III) at 752 mV were observed.|
