Inhibitive and Adsorption Properties of Ethanolic Extract of Fruit of Azadirachta Indica on the Corrosion of Copper in HCL

Abstract

ABSTRACT:The inhibition potential of Azadirachita indica fruit extract on the corrosion of copper immersed in 0.5 N HCl at the room temperature (30°C) was investigated by the help of weight loss method. From the weight loss values, corrosion rates were determined. In the results obtained, the fruit extract, in hydrochloric acid medium, gave its best corrosion inhibition performance at 1.052 g/L extract concentration. The corrosion, kinetic and adsorptive parameters were calculated.

Synthesis, Characterization and Electrochemical Studies on the Corrosion Inhibition Properties of Schiff Bases for Mild Steel in 1 M HCl Solution

“…The procedures were repeated for ten hours at 303K. The differences in weight of the coupons were again taken as the weight loss" [21].The corrosion rate (CR), inhibition efficiency (IE), and degree of surface coverage (Ө) of mild steel in 1M HCl solution was computed using the formula:…”

Recent developments in materials for aluminum–air batteries: A review

“…Using a weight loss method, Yadav et al [101] studied an extract of the Ziziphusmauritiana fruit as a green corrosion inhibitor for Al in HCl solution. It was tested at room temperature and for various extract concentrations between 0.0644 g/L and 1.288 g/L.…”

Corrosion Inhibition of Aluminum in 0.5 M HCl by Garlic Aqueous Extract

“…The corrosion behaviour of Aluminium and copper exposed to HCl solution and their inhibition in HCl containing 0.0644 -1.288 g/L Ziziphus mauritiana Fruit Extract used as inhibitor was studied at room temperature using weight loss method 20 . From weight loss data it was observed that the Inhibition efficiency increases with increase in concentration of the inhibitor reaching a maximum of 76.8% at room temperature for aluminium and 88.58% at room temperature for copper at 1.288 g/L concentration of EEZmF.…”
