Ascorbic Acid as Corrosion Inhibitor for Steel in Alkaline Media Containing Chloride Ions
The investigation of nature-designed molecules and blends of naturally synthesized chemical compounds as possible inhibitor candidates for reinforcing steel in concrete is of raising interest due to the health and environmental hazards involved in the use of most inorganic corrosion inhibitors. In the alkaline media of concrete pore solution, the oxide film is present on the surface of the rein...
متن کاملSYNERGISTIC INFLUENCE OF NITRITE ON INHIBITION OF MILD STEEL CORROSION IN CHLORIDE CONTAMINATED ALKALINE SOLUTION
Corrosion behavior of mild steel in chloride contaminated alkaline solution has been studied for the period up to 100days. Saturated Calcium hydroxide solution was used as alkaline solution and 0.5M NaCl solution was used to accelerate mild steel corrosion. The Charge transfer resistance Rct, Current density Icorr and inhibition efficiency values were obtained from tafel polarization and electr...
متن کاملSynergistic 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...
متن کاملAbsorption of Lead Ions by Various Types of Steel Slag
Steel slags are the by products of steel industries, which forms during reduction process of iron melting. The chemical composition of it changes depending to the melting procedure. Its mineralogical composition also varies based on the cooling procedure. Two different types of steel slag were used as absorbing bed for various concentrations of Pb2+ ions in the form of lead chlor...
متن کاملThe Synergistic Effect of Iodide and Sodium Nitrite on the Corrosion Inhibition of Mild Steel in Bicarbonate–Chloride Solution
The effect of potassium iodide (KI) and sodium nitrite (NaNO₂ inhibitor on the corrosion inhibition of mild steel in chloride bicarbonate solution has been studied using electrochemical techniques. Potentiodynamic polarisation data suggest that, when used in combination, KI and NaNO₂ function together to inhibit reactions at both the anode and the cathode, but predominantly anodic. KI/NO₂- conc...
