Kinetics and adsorption behaviour of benzoate and phthalate at the -alumina–water interface: Influence of functionality
نویسندگان
چکیده
A systematic study on the influence of functionality on adsorption of benzoate and phthalate at -alumina–water interface was investigated. Kinetics of adsorption of benzoate and phthalate on -alumina surfaces were performed at constant ionic strength, I= 5× 10−4 mol dm−3 and pH 5 at 25, 30 and 40 ◦C. Kinetics results show that the rate of adsorption of phthalate is ≈2 times more than that of benzoate on -alumina surfaces at 25 ◦C. The adsorption of benzoate and phthalate on -alumina surfaces were carried out over a wide range of concentration of adsorbate at fixed ionic strength, I= 5× 10−4 mol dm−3 and pH 5–10. The adsorption isotherms for both the systems were found to be L s s a t F t s ©

Synergistic Influence of Benzoate Ions on Inhibition of Corrosion of Mild Steel in 0.5m Sulfuric Acid by Benzotriazole
The influence of benzoate anions on the corrosion inhibition effect of benzotriazole (BTA) for mild steel in sulfuric acid has been investigated. The investigation was carried out by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. The addition of benzoate ions greatly enhances the inhibition efficiency of BTA in a synergistic manner. This effect has bee...
