| Abstract: | The adsorption of benzalkonium chloride on a surface of St3 steel in 0.1 N HCl + 0.9 N KCl and 0.9 N HCl + 0.1 N KCl solutions
is studied using impedance spectroscopy. Taking into account the surface coverage of the electrode with the inhibitor, the
true rate constants of the main stages of the cathodic hydrogen evolution and solid-phase diffusion of hydrogen, as well as
the surface coverage with hydrogen in the solutions studied, are calculated. |
