Effect of expired paracetamol–Zn⁺²system and its synergistic effect towards iron dissolution inhibition and green inhibition performance

Synthesis, characterization, and evaluation of polymeric surfactants derived from PET plastic waste as green corrosion inhibitor of steel surfaces in marine environment for heavy industry

“…Thermometric measurements depend on measuring the temperature variation during the reaction of a metal with a test piece with a definite volume of a corroding solution. 34–39 The variation in the temperature of the system was monitored with time, and the reaction number (RN) is defined as 34–39 RN (°C min −1 ) = ( T m − T i )/ t m where T m and T i are the maximum and initial temperatures, respectively, t m is the time in minutes taken to attain the maximum temperature.…”

“…High salinity, falling pH, chloride ion presence, and temperature accelerated the corrosion of iron samples in the solution. [34][35][36] When iron is exposed to oxygen, humidity, and chloride ions, a complex process known as iron corrosion occurs. Following the characteristics of the corroding material allows the calculation of the societal costs of the corrosion of iron structures or other components.…”

“…Reaction number (RN) values are known as a relative measure of the retardation of the dissolution process. [34][35][36][37] The extent of corrosion inhibition can be expressed in terms of the percentage reduction in the reaction number (RR%) given by the following equation. [34][35][36][37]…”

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

“…Corrosion inhibitors are substances that are added in very small quantities for limiting the corrosion process by either inhibiting the anode or cathode reactions or both. − Corrosion inhibitors contain effective functional groups that enable them to be adsorbed on the metal surface such as hydroxyl and amine groups, as well as oxygen, nitrogen, sulfur, and heterocyclic materials. Organic and inorganic materials have been used as metal corrosion inhibitors in acidic, alkaline, and saline corrosive media and marine environments. − Environmental waste is recycled, and the results of recycling are used as metal corrosion inhibitors, whereas the waste of PET and PEAA plastics is recycled, and the recycled products are used as corrosion inhibitors for carbon steel used in the petroleum industry in acidic media and marine environments. − The surfactant materials prepared from plastic waste had an effective activity in adsorption on the surface of metals and protection of metals from corrosion, − as well as expired drugs were used as inhibitors. − Polymeric materials and heterocyclic compounds − were used to protect metals from corrosion. Corrosion of metals is a pervasive process related to the industry and to the daily use of metals in the environment.…”

Computational modelling and correlation of physical parameters of 1-heptatriacotanol, phytol and 3, 7, 11, 15-tetra methyl-2-hexadecen-1-ol with the corrosion inhibition efficiency of CIW for mild steel in HCl

“…Both electrochemical and chemical techniques were utilised for evaluating the corrosion inhibition performance of expired paracetamol-Zn2 + system for iron in NaCl medium. Adsorption, adhesion and protective layer formation of the inhibitor systems are the key reasons for its corrosion inhibition mechanism [26].…”
