عنوان انگلیسی Electrochemical Examination of an Eco-friendly Corrosion Inhibitor "Almond Flower Extract" for Carbon Steel in Acidic Medium (1 M HCl)
چکیده انگلیسی مقاله Green inhibitors have recently captured the attention of researchers to achieve good performance to inhibit and minimize corrosion with low environmental effects. For this reason, in this work, Almond flower extract (AFE) was used as a natural inhibitor to reduce the corrosion rate of carbon steel in an aggressive solution 1M HCl. The inhibition efficiency (IE%) of this extract was examined via different experimental methods such as Potentiodynamic polarization (PDP) and Electrochemical impedance spectroscopy (EIS) for five concentrations from 0.5 to 2.5 g/L. The outcomes denoted that the inhibitory impact increased with the rising concentration of flower extract up to 2.5 g/L and subsequently decreased with increasing concentration. PDP results reveal that (AFE) is a mixed-type corrosion inhibitor, the adsorption of this flower extract compounds followed the Langmuir isotherm, and its (IE%) of 2.5g/L (AFE) can exceed 96% at 293 K. The inhibitory impact of Almond flower extract was studied at different temperatures ranging from 293 K to 323 K. The inhibition performance of (AFE) remained virtually constant with rising immersion time, depending on the results of the EIS.
