## Abstract The electrochemical behavior of pure copper has been studied in aqueous environments using linear polarization and electrochemical impedance spectroscopy (EIS) techniques as a function of immersion time. The effect of pollutants (like chloride, sulfide and ammonium ions) on the nature o
Tlne properties and the composition of the surface film have been studied by using the potentiostatic step method . The current density decay curves at different temperatures have been studied in order to establish the mechanism of film formation . By using surface analytical methods, ie SAM, Auger
