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.
