WITHDRAWN: Anticorrosive concert of expired drug acts as novel and potent inhibitor for deterioration of Low carbon steel in acidic Environment

“…This corrosion should be avoided or controlled otherwise it destroy the unique properties of low carbon steel. In India the cost of scale wastes from the industries is 26.1 billion USD, it is equal to 2.4 % of total GDP [1--9], the different types of heterocyclic organic compounds containing N, O, S and P molecules has been noted as corrosion inhibitors, The speci c was adsorbed on the low carbon steel surface and removed the metal's corrosion active sites, [10][11][12][13][14][15][16][17][18][19][20][21][22]. The following three major factors in uence inhibitor adsorption: metal type and nature, chemical structure of the inhibitor molecule, and medium of the metal present.…”

“…There is a relationship between E HOMO and IE and EA with (E LUMO ) as follows IE=-E HOMO (14) The low ionization energy results the removal of electron from the outermost orbital. The relation is as follows.…”

Manufacturing of Corrosion Inhibitors and Flow Improvers from Recycling of Waste at Hail City, Saudi Arabia: Physicochemical and Electrochemical Studies on Steel in Petroleum Industries

“…The values of R ct in Table increase as the doses of the PETAA inhibitor are increased, and this increase may be caused by the development of an adhering coating on the surface of the steel. This is due to a decrease in charge transfer between the steel surface and the corrosive medium caused by the addition of PETAA inhibitor molecules, which promotes the adsorption of PETAA’s amido amide functional groups across the carbon steel surface. − In addition, the C dl values drop with increasing PETA inhibitor dosages, which typically happens when the dielectric constant falls. This is explained by the inhibitor’s elements adhering to the steel/electrolyte interface and shielding the steel from the hostile medium.…”

“…Chemical, analytical, and electrochemical techniques were used for the evaluation of the synthesized nanoparticle–expired drug inhibitor system as an inhibitor for carbon steel (SABIC steel). Recently, polymeric surfactant materials have been used on a large scale for the protection of metals and alloys in industrial fields; − the nonionic surfactants derived from oxadiazole and thiadiazol were prepared, characterized, and evaluated as inhibitors for carbon steel in a hydrochloric acid medium. Chemical (weight loss) and electrochemical [pour point depressant (PPD) and EIS] techniques were utilized for testing the inhibition efficiency and studying the inhibition mechanism .…”

“…In the work reported by Abdallah et al, the inhibition of the nonionic surfactant derived from oxadiazole and thiadiazol reached 89%. Abdallah and co-workers in 2022 studied the effect of some polymeric surfactant materials on the protection of SABIC iron in the hydrochloric acid corrosive medium by experimental and theoretical quantum chemical studies . Protection of carbon steel materials in the acidization of oil and gas wells was studied by Zarrouk and Abdallah et al in 2022 using cationic gemini surfactant materials, and experimental and computational theoretical studies were performed for the interpretation of corrosion inhibition .…”
