A study on behavior of bamboo charcoall in corrosion inhibition

Abstract

This research is to investigate the corrosion rate of steel nail at different burning temperature of bamboo charcoal. The corrosion rate of steel nail with and without addition of sodium benzoate in bamboo charcoal is also investigated. Analysis of Scanning Electron Microscopy was carried out to analyze the microstructure and macrostructure pores within bamboo charcoal. The images obtained from the analysis showed that bamboo charcoal had larger pores size with higher burned temperature of bamboo charcoal. The larger pores making the bamboo charcoal become high adsorption capacity. Besides that, analysis of X-ray Fluorescence (XRF) had shown that bamboo charcoal consist of several minerals. In analysis of XRF, bamboo charcoal at different burned temperature was used. Also, electrochemical impedance spectroscopy (EIS) was employed to study the corrosion behavior of steel nail in tap water. The result showed that bamboo charcoal at higher burned temperature of bamboo charcoal and addition sodium benzoate in bamboo charcoal have a lower corrosion rate of steel nails. As a summary, this study showed that bamboo charcoal at 700 C burned temperature and with addition sodium benzoate in bamboo charcoal were efficient in corrosion inhibitor.
