Abstract

This study aimed to investigate the ability of Eleutherine americanna Merr. extract as an environment friendly inhibitor for API 5L X42 in 1M HCl. Corrosion inhibition ability of this extract was tested using tafel polarization, weight loss and electrochemical impedance spectroscopy methods. FTIR test was used to investigate flavonoid and antioxidant compound that play an important role to inhibit the corrosion process. In this study, the concentration of Eleutherine americanna Merr. extract used was 0 ppm, 100 ppm, 250 ppm, 500 ppm, and 1000 ppm. The corrosion rate decreases within the increasing of inhibitor's concentration. The highest percentage inhibition efficiency was found to be 84.5% at 1000 ppm. It can be concluded that Eleutherine americanna Mer. extract can be used as an alternative and environmental friendly inhibitor for API 5L X42 in 1M HCl.
