Abstract: Surface layers formed by adsorption of 5-chloro-1,2,3-benzotriazole (5-chloroBTA) on nickel and influence of pH of borate buffer solution and electrode potential on formation multicomponent oxidized films on nickel were studied by XPS. It was found that at concentration of 10–4 mol/l in neutral borate solutions a 0.7 nm monomolecular layer of 5-chloroBTA is formed. Using peak intensity angular dependence of XPS spectra the orientation of 5-chloroBTA close to vertical on nickel hydroxide formed on the nickel surface was shown. 5-ChloroBTA forms a chemical bond by lone pair of nitrogen and surface nickel cations.
