Rice Husk Extracts Ability to Reduce the Corrosion Rate of Mild Steel

M. Pramudita, Sukirno, and M Nasikin
Abstract—Rice husk extracts ability to reduce the corrosion rate of mild steel in 1 M H2SO4 solution was studied using weight loss technique. XRD analyzed silica structure of rice husk extracts. The Inhibitor was added in various concentrations (0, 10, 15, 20 and 25 ppm) at different immersion times (2, 4 , 6 and 8 h). The results obtained indicate that rice husk extract acts as a good inhibitor for mild steel. Rice husk extract was able to reduce corrosion rate up to 4.77 mmpy with inhibition efficiency exceeded 90 in 1 M H2SO4 solution. X-ray Diffraction (XRD) analysis shows the silica structure present in rice husk extracts is amorphous, thus makes it more environmentally friendly.

Index Terms—Rice husk extract, bio corrosion inhibitor, natural resources.
