Congo Red Dye As A Novel Corrosion Inhibitor for Zinc in Hydrochloric Acid Solution
نویسندگان
چکیده
The inhibitive effect of congo red was examined as corrosion inhibitor for the corrosion of zinc in 1N HCl by conventional weight loss and gasometric methods. Results obtained show that congo red exhibited high inhibition efficiencies. The inhibition efficiency was found to increase with increase in the inhibitor concentration. The adsorption of the inhibitor molecules on the zinc metal surface obeyed Temkin adsorption isotherm.

Investigation of Furfural as Corrosion Inhibitor in Hydrochloric Acid Solution
Effectiveness of furfural as an organic inhibitor in 5 percent hydrochloric acid which is used in acid pickling of steel was evaluated. Lungmuir, Frumkin and Flory-Huggins isotherms [1, 2] were used to determine the parameters of effective adsorption, free energy and entropy of adsorption. Furfural indicated an inhibition less than 17 percent in concentrations of 0.001 mole per liter for a dura...
