Abstract:

The inhibition of the corrosion of zinc in 4 M HCl by Naproxen has been investigated at room temperature using weight loss measurements. Results obtained showed that Naproxen is a good inhibitor and its inhibition efficiency (IE %) increased with the increase of inhibitor concentration since it was 82%. The surface coverage was 0.82 at 300 ppm inhibitor concentration, hence the optimum concentration was 300 ppm.
