Abstract

Satirn is a type of the pesticides has been evaluated as green inhibitor for the corrosion of the galvanized iron in saline solution which was investigated by chemical and electrochemical measurements. The results of polarization showed that satirn acts as mixed type inhibitor. Inhibition was found to increase with the increase of satirn concentration reaching to approximately 90% at 250 ppm. The inhibitive action was discussed by the adsorption of a stable complex on the metal surface. The adsorption of satirn on the metal surface obeys Temkin adsorption isotherm. Satirn has a slightly effect on Escherichia Coli and can be applied safely in sanitation plants.
