Abstract

This research objective was to investigate secang heartwood extract (caesalpinia sappan l) as a corrosion inhibitor on carbon steel metal (API 5L Gr B) in 3.5% NaCl environment. This research utilized polarization linier for the measurement method. Secang extract was adequate to reduce corrosion rate by 53.18% efficiency (based on polarization measurement). The most effective concentration of inhibitor secang was 2.0 ml/400 ml 3.5% NaCl. Furthermore, inhibitor efficiency of secang has tended to decrease by increasing of temperature. From polarization study, secang was indicated as mixed type inhibitor, with predominant cathodic effectiveness. In addition, the inhibition mechanism of secang was shown as physicsorption mechanism and obeys Langmuir Isotherm model.
