“…Equation 2 was used to calculate the IE percentage: where ΔW and ΔWi represent the MR per unit area in the absence and presence of prepared samples, respectively. This measurement was performed in accordance with ASTM standard G 31–72 35 . The MR —time curves for C-steel in the presence and absence of changed dosages ranging from 5 × 10 –6 to 25 × 10 –6 M for SC1 and SCP2 are shown in Fig.…”

The effects of [Co2 (SCN) 4(hmt)2(H2O)6. H2O] (SC1) and [Co (CN)6 (Me3Sn)3(H2O). (qox)] (SCP2) MOF as corrosion inhibitors on C-steel in 0.5 M sulfuric acid solutions are illustrated utilizing mass reduction (MR), electrochemical [potentiodynamic polarization (PP), and AC electrochemical impedance (EIS)]. The experiments revealed that as the dose of these compounds rose, the inhibition efficacy (IE percent) of C-steel corrosion improved, reaching 80.7–93.1% at dose 25 × 10−6 M for SC1 and SCP2, respectively. IE percent, on the other hand, dropped as the temperature range grew. SC1was adsorbed physically and chemically (mixed adsorption) but SCP2 was adsorbed physically on the surface of C-steel and conformed to the Langmuir adsorption isotherm equation. The PP studies revealed that these compounds act as mixed kind inhibitors. To establish the morphology of the inhibited C-steel surface, scanning electron microscopy (SEM), energy transmitted X-ray (EDX), and atomic force microscopy (AFM) studies were used. All tested experiments were in good agreement.

“…The drug was supplied from a variety of pharmaceutical companies. In a stock solution, 1000 ppm" [33] were made by dissolving the required weight of drug (1 g) in a small amount of one molar HCl. Using a water thermostat set to ± 0.5 °C, measurements were taken at 30-50 °C.…”

“…This can be explained by the fact that the dissolution procedure is caused by covering the active sites located on the surface of the Al. This also indicates that the dissolution mechanism that is not affected by the presence of Candesartan drug [33]. If the variation in corrosion potential (E corr ) values is more than  85 mV in the presence and absence of Candesartan drug, the inhibitor molecules are named anodic or cathodic type and this did not happen because, the potential of corrosion values displacement fewer than 85 mV [35].…”

The corrosion performance of aluminum in 1 M hydrochloric acid solution in the existence and absence of Candesartan drug was examined utilizing, potentiodynamic polarization (PDP) and AC impedance (EIS) tests. It was found that the inhibition efficacy (%IE) of Candesartan drug was influenced by its doses and temperature and reached to 92.9% at 40x10-6 M, 30oC. The adsorption isotherm agreed with Langmuir model. From Tafel data the investigated Candesartan drug acts as mixed kind inhibitor. The influence of temperature on the rate of dissolution and the thermodynamic parameters in the existence and absence of Candesartan drug were also, studied and explained. All tests gave similar results.
