Insight of corrosion mitigation performance of SABIC iron in 0.5 M HCl solution by tryptophan and histidine: Experimental and computational approaches

Investigation of the anticorrosion and adsorption properties of two polymer compounds on the corrosion of SABIC iron in 1 M HCl solution by practical and computational approaches

“…To choose a suitable isotherm for this adsorption, the surface coverage values ( θ ) were applied to several isotherms. The results obtained confirmed that the preferable isotherm was the Langmuir isotherm, which can be given by: 54 where C polymer is the concentricity of the polymer used and K ads is the equilibrium constant of adsorption.…”

“…13 , for the dimer of butylene terephthalate the HOMO was concentrated on the benzaldehyde moiety and LUMO in the terephthalate region, while the HOMO and LUMO distributions of the dimer of styrene were the same, indicating a high chance of electron transfer from the HOMO to the LUMO with bonding formation between the tested reagents. 54 The high values of E HOMO are likely to indicate a molecule's tendency to donate electrons to suitable acceptor molecules with empty molecular orbitals. The LUMO energy reflects a molecule's ability to receive electrons.…”

Appraisal of synthetic cationic Gemini surfactants as highly efficient inhibitors for carbon steel in the acidization of oil and gas wells: an experimental and computational approach

“…This confirms that the examined CGS-molecule is classified as an anti-corrosion of the mixed type. 39 It appears that this CGS-molecule is simply adsorbed onto the CS-surface by covering the active sites, with no effect on the anodic and cathodic reaction mechanisms. 38 This can be explained by the CGS-molecule adsorption onto the CS-surface.…”

A review of amino acids used as corrosion inhibitors on iron metal/alloys in aggressive environments

“…Maximum IE of 92.09% for tryptophan and 89.37% for histidine at a concentration of 500 ppm and 30 o C using the PDP method. IE increased with concentration but reduced with temperature (using the mass loss method) [177] Thiazolidine-2,4diones (TZD) and its amino derivative 2aminothiazolidin -4-one (AT).…”
