Résumé

The acid corrosion inhibition process of armco iron in hydrochloric acid 1 M HCl by a modified polyphosphate derivatives of guanidine and urea copolymer (PGUC) has been investigated using electrochemical impedance spectroscopy (EIS). The effect of a thermal treatment of the copolymer on the corrosion behaviour was studied. Data obtained from Electrochemical Impedance Spectroscopy (EIS) show a frequency distribution and therefore a modelling element with frequency dispersion behaviour, a constant phase element (CPE) has been used. The PGUC derivatives have also been used as biocides in aqueous environments and the bacterial killing efficiencies have been determined.
