Study of the inhibition effect of two novel synthesized amido‐amine‐based cationic surfactants on aluminum corrosion in 0.5 M HCl solution

Abstract

Two novel amido‐amine‐based cationic surfactants, namely, 3‐decanamido‐N,N,N‐trimethylpropan‐1‐aminium methyl sulfate (DAMS) and N‐(3‐decanamidopropyl)‐N,N‐dimethylbutan‐1‐aminium bromide (DABB) were prepared and their chemical structures were elucidated via various spectroscopic tools. The surface activities of the targeted prepared surfactants were investigated. Utilizing potentiodynamic polarization, hydrogen evolution, and weight loss methods, the inhibition impact of both synthesized surfactants on aluminum corrosion in solution with 0.5 M HCl was studied. The effect of raising both temperature and surfactant concentration on the inhibition efficiency was studied and the thermodynamic functions were calculated and clarified. Langmuir adsorption isotherm fitted widely with the empirical data. At all concentrations and temperatures, it was found that the inhibition efficiency for DAMS is greater than that of DABB.

Combination of practical and theoretical measurements of albumin egg as an eco-friendly inhibitor for copper corrosion in alkaline solutions

“…Albumin egg spontaneously adsorbs onto the copper surface, as proved by the negative value of . 52 The obtained significantly small value suggests that the nature of adsorption of albumin egg onto the copper surface is physical. 24…”

An examination of the effectiveness of the expired drug isoprinosine in preventing aluminum corrosion in alkaline solutions using both computational and experimental techniques

“…The required electrochemical parameters are shown in Table 1 and include the percentage of inhibitory efficacy (% I. E. P), surface coverage ( θ ), corrosion current ( i corr ), cathodic and anodic Tafel slopes ( β a and β c ) and corrosion potential ( E corr ). With a view to computing the (% I. E. P) and surface coverage ( θ ), the following eqn (2) and (3) were used: 50–54 where i NaOH and i iso are the corrosion current density of the aluminum electrode in lack of and existence of isoprinosine, respectively.
