Abstract

The effect of some hydrazone oxime derivatives on the corrosion of iron in 2M HCl have been studied by polarization and weightโ€loss techniques. It was found that the compounds under consideration are adsorbed on the iron surface according toe the Temkin isotherm. The Tafel slope is approximately constant independent of the concentration of the inhibitor. The results of polarization indicate that all compounds tested were of a mixed type, but the cathodic is more preferenially polarized.

The inhibition efficiency was found to follow the order:I>III>IV>VI>II.

## Abstract The inhibiting effect of some phenols on the corrosion of iron in 0.5 N hydrochloric acid depends from the concentration and the constitution of the particular inhibitor. The effect decreases in the following order; pโ€thiocresol > pyrogallol > resorcinol > phenol > pโ€cresol > mโ€cresol >
