Abstract

In the current study, weight loss measurements and electrochemical methods were used to examine the inhibitory characteristics of the aqueous extract of Ribes nigrum leaves on the corrosion of carbon steel in hydrochloric acid medium. It has been determined that in 1.0 mol·dm-3 HCl, the inhibition efficiency of the extract can reach up to 92,66%. Metal protection ability was found to increase with increasing inhibitor concentration. It was observed that high inhibition efficiency is a result of spontaneous physisorption of the inhibitor (ΔG0abs ˃ -20 kJ·mol-1) on the carbon steel surface directly obeys the Langmuir absorption model. The polarization curves analysis revealed the mixed-type inhibition behavior of the studied extract with the highest inhibition efficiency achieved at inhibitor concentration of 2.0 g·dm-3. The electrochemical and gravimetric data were found in great agreement. The assumption that the inhibitory effect of the extract is caused by the adsorption of phenolic compounds was made by the performing of UV-vis spectrophotometric analysis of the corrosive medium before and after the immersion of the carbon steel specimen. Aqueous extract of the R. nigrum leaves was proposed as a low-cost, environmentally friendly and effective corrosion inhibitor.
