“…The results also suggest that in case of (Gelatin, Agar) the adsorption of the inhibitor is weaker and the adsorption of the inhibitor takes place [20]. For Cellulose acetate and to a certain extent for Starch also, the adsorption bonds appear to be stronger and resist the adsorption.…”

“…The variety of inhibition efficiency of drugs (Amoxicillin, Cefixim and Cephalexin) is due to the variety of the molecular structure and atomic active centers of suggested drugs [22]. The reducing rate of corrosion by using different drug concentrations could be explained by formation a protective barrier by molecules of drugs on the metal surface [ 23]. The adsorption isotherms are useful calculation to elucidate thethe nature of interaction among the organic molecules and surface of metals.…”

This work is focusing on some drugs (Amoxicillin, Cefixim and Cephalexin) to use as corrosion inhibitors for the mild steel in 1M H2SO4 aqueous solution. Weighting loss measurements were used for 24 hours at 30 o C. The results of corrosion process showed that higher inhibition efficiency values of these drugs have obtained with the highest concentration. The increasing of inhib itor concentration was accompanied with corrosion rate to be decreased, inhibition efficiencies increased and surface coverage degree increased. The adsorption free energy values were predicted physisorption effect for (Amoxicillin, Cefixim and Cephalexin) which explained the interaction nature between the organic molecule as corrosion inhibitors and metal surface.

“…All measurements were performed using 0.5 M HCl without stirring in atmospheric conditions. A stabilization period of 30 minutes was allowed prior to the electrochemical measurements, which has been proven to be sufficient to attain a stable open-circuit potential (OCP) 18,19 . To verify the data, each measurement was performed in triplicate.…”

In this study, the improvement in the corrosion inhibition efficiency of a natural inhibitor (coriander seed extract) incorporated with zinc oxide nanoparticles (np-natural inhibitor) was investigated using the gravimetric method and electrochemical methods. The weight loss method indicated that a 25.7% and 57.1% inhibition efficiency (I%) were found when using 0.66 g/L of natural inhibitor and np-natural inhibitor, respectively. Moreover, as the temperature increases, the I% also increases for both inhibitors, suggesting a chemisorption mechanism. EIS revealed that the polarization resistance value (R p ) of np-natural inhibitor is greater than that of the natural inhibitor, indicated that np-natural inhibitor was more resistive. The Temkin adsorption isotherm gave the best fit for both the inhibitors. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) showed the surface morphology of the zinc metal in the absence and presence of both the inhibitors.
