Progress on pharmaceutical drugs, plant extracts and ionic liquids as corrosion inhibitors

Abstract

In the past, lives and wealth have been lost due to corrosion in almost all engineering fields. Not only this, the cost of reviving damaged equipments in the industry due to corrosion contributed a lot to the gross domestic product of a nation. Thus, all hands must be on desk to combat this harzadous act via time to time research on its final resolution. However, current research works have revealed effective and reliable corrosion inhibitors from pharmaceutical drugs, plant extracts and ionic liquids as organic green corrosion inhibitors (OGCIs) with accommodative attributes such as being environmentally friendly, readily available, biodegradable, non-harmful, relatively cheap and many others to mention a few. This paper opens readers mind into the detailed classifications, mechanisms and active functional groups of these eco-friendly OGCIs. Not only the corrosion efficiency calculation ways but also influencing factors on efficiency were presented. Plant extracts, pharmaceutical drugs, ionic liquids and synthetic inhibitors, as among major sources of OGCIs, used in preventing material corrosion in corrosive media were separately and comprehensively examined. The significance of values obtained from simulating presented mathematical models governing OGCIs kinetics, adsorption isotherm and adsorption thermodynamics was also included. In conclusion, beneficial recommendations for both current and prospective researchers in the field of Corrosion Engineering were presented.

Syntheses of novel 1,5‐benzodiazepinederivatives: Crystal structures, spectroscopic characterizations, Hirshfeld surface analyses, molecular docking studies,DFTcalculations, corrosion inhibition anticipation, and antibacterial activities

“…[ 40 ] As a solution to overcome this problematic, the use of corrosion inhibitors, such as organic‐based compounds, is required. [ 41 ] Recently, the Monte Carlo simulations have been used to investigate the adsorption process of several organic inhibitors onto different metallic surfaces. [ 42 ] Conferring to the obtained computational data, the adsorption energy (or binding energy) was effectively correlated with the observed inhibition effectiveness.…”

The role of pH in corrosion inhibition of tin using the proline amino acid: theoretical and experimental investigations

“…Accordingly, the use of corrosion inhibitor compounds is practical and an attractive method. 3 To date, several organic molecules have been used as corrosion inhibitors, and among them, amino acids have been broadly investigated as ecofriendly and cheap anti-corrosion compounds for different metallic materials in various corrosive environments. [4][5][6][7][8][9][10] In addition to the ecological advantage of amino acids, they are characterized by the presence of different heteroatoms (e.g., O, N and S) and eventual unsaturated bonds within their molecular skeletons.…”

Inhibition of Aluminum Alloy 7025 in Acid Solution Using Sulphamethoxazole

“…Drugs are nontoxic and cheap, so most of them can be produced from natural materials thus they would be insignificant negative influences on the environment. Accordingly, it would be a good alternative for the previous traditional toxic inhibitors [15,16]. The drugs selection as corrosion inhibitors depends on (O, N and S) as effective centers and they can be produced and purified straightforwardly [17][18][19][20].…”
