Electrochemical and XPS study of 2-merсaptobenzothiazole nanolayers on zinc and copper surface
2014
The electrochemical behavior of copper and zinc in neutral (рН 7.4) borate buffer solution with addition of 0.5 M NaCl and the effect of 2-merсaptobenzothiazole (MBT) on the electrochemical processes and adsorption on these metals has been studied by means of electrochemistry and X-ray photoelectron spectroscopy (XPS). The formation of MBT– metal cation complex films on copper and zinc surface has been shown. The effect of corrosive media composition and time-dependent relations of nanoscale film growth on the surface of the metals investigated have been determined. It was assumed that adsorbed MBT anion forms M(MBT)х, a polymeric complex where M = Cu + (x = 1) or Zn 2+ (x = 2).
