“…[I corr (uncoated) − I corr (coated)]/I corr (uncoated) × 100 where I corr (uncoated) and I corr (coated) are the corrosion current density values without and with inhibitor, respectively. The decreasing inhibition performance as the temperature of the solution rises might be explained to an increase in the mobility of the inhibitor molecules, resulting in a reduction in the contact between the inhibitor molecules and the carbon steel surface [16][17].…”
The corrosion inhibiting properties of the new furan derivative 5- (furan-2-ylmethylsulfonyl-4phenyl-2,4-dihydro [1,2,4] triazole-3-thione in acidic solution (1.0 M HCl) were explored utilizing electrochemical, surface morphology (AFM), and quantum chemical calculations approaches. The novel furan derivative 5-(furan-2-ylmethylsulfonyl-4-phenyl-2,4-dihydro [1,2,4] triazole-3-thione shows with an inhibitory efficiency value of 99.4 percent at 150 ppm, carbon steel corrosion in acidic medium is effectively inhibited, according to the results. The influence of temperature on corrosion prevention was studied using adsorption parameters and activation thermodynamics. The novel furan derivative creates a protective layer over the metallic surface that separates the metal from harsh acid solution and thereby protects it from destructive disintegration, according to the AFM study. The experimental findings are supported by the theoretical method of density functional theory (DFT) at the B3LYP/6-311 ++G basis set for inhibitor.
“…These medications include a variety of organic chemicals that can be utilized as anti-corrosion agents to lessen metal dissolution. 21–44 One of the common drugs used to treat herpes is isoprinosine. It is possible to reuse isoprinosine, which is not sold, as an inhibitor for metal corrosion.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
