Study the antibacterial activity and inhibition effect of reactive red (31)‎ dye for the corrosion of carbon steel in corrosive media

الملخص EN

The inhibitive action of Reactive Red (RR31) dye against corrosion of carbon steel in 1M acetic acid has been studied using gravimetric method at temperature ranged (288-318)K.

The antibacterial actsolutionivity for the different concentrations of RR31 dye against different bacterial species was studied.

The experimental data indicates that this dye acts as a potential inhibitor for carbon-steel in acetic acid medium and the protection efficiency increase with increasing (RR31) dye.

The adsorption of (RR31) dye on the carbon steel surface was found to follow Langmuir adsorption isotherm.

Thermodynamic data for the adsorption process such as Gibbs free energy change AGads, enthalpy change AHads, and entropy change ASads were estimated.

The results showed that the different concentrations of RR31 dye has antibacterial ability.
