Costus Afer

Inhibition effect of Costusafer on mild steel in 0.5 M HCl was studied using gravimetric method at room temperature. It was found out that Costusafer inhibited the corrosion of mild steel in the acidic environment and that the efficiency of inhibition increased as the concentration of the inhibitor in the environment increased. The data was used to test different isotherms and it suited the Langmuir isotherm. A value of -15.995 kJmol-1 was gotten for the ∆Goads. This value showed that the extracts of Costusafer inhibited the corrosion process through physiosorption mechanism. The high value of inhibition efficiency of the extract as the concentration increased in rationalized in terms of the increase in herteroatoms, saponnins and tannins which are present in the extract.

Maximum Inhibition

The inhibition efficiency of mild steel corrosion in HCl acidic solution containing various concentrations of mixed inhibitors were evaluated by conducting Tafel polarization and electrochemical impedance studies. The mixed inhibitors used in this present investigation were trisodium citrate and sodium benzoate. In this present investigation 0.01 N to 0.1 N concentrations of HCl was used at 30°C. Sodium benzoate present in the mixed inhibitive system enhanced the inhibition efficiency through chemisorptions. The maximum inhibition efficiency ( 95.4%) was obtained for the mixed inhibitive system containing 0.05 M citrate and 0.5 M benzoate in 0.1 N HCl.
