Abstract
A study of the electrochemical characteristics of glassy carbon electr odes modified by polyethyleneimine films with different degrees of cro ss-linking when the acidity of the supporting electrolyte changes is c arried out. It is shown that as the degree of cross-linking increases, the stability of the films and the formal coefficient of the charge d iffusion also increase. An increase in the solution pH leads to a decr ease in the number of redox anions taking part in the electrode proces s.
