The electrochemical redox behavior of Cu(II) has been investigated at glassy carbon electrode (GCE) in Britton-Robinson (BR) buffer as well as in a mixture of BR buffer and potassium chloride media. It is apparent that BR buffer can act as a supporting electrolyte and modify the electrochemical behavior of Cu(II) ion in aqueous medium. In BR buffer medium, Cu(II) undergoes one two-electrons redox process, while in a mixture of BR buffer and KCl media it follows two one-electron electrochemical reaction routes. Because of the formation of hydrogen bridge bond between the supporting electrolyte and GCE surface, the Cu(II) ion follows Cu(II)/Cu(0) electrochemical reaction path, while in presence of KCl such a hydrogen bridge bond is not formed and it undergoes successive Cu(II)/Cu(I) and Cu(I)/Cu(0) electrode reaction processes. Moreover, the linear variation of peak current with the square root of scan rate indicates that the electrochemical redox processes are diffusion controlled.

Abstract We utilized the high resolution of microwave Fourier transform spectroscopy to investigate the 14N-hyperfine structure of trans-2,2,2-trifluoroethylamine, CF3CH2NH2, trans-isopropylamine, CH3CHNH2CH3, and aminoethanole, HOCH2CH2NH2, and the amino deuterated isotopomers trifluoroethylamine-d2 and isopropylamine-d2. The complete coupling tensor of trifluoroethylamine could be determined. We found that the fluorine atoms have a distinct effect on the nitrogen electronic surrounding of the named molecule, presumably through a hydrogen bridge bond between two of these atoms and the amino protons. For isopropylamine and aminoethanole wrong values of the coupling constants known in the literature could be corrected
