    (2014-05-21) Othman, Norinsan Kamil; Yahya, Solhan; Mohamad, Nadzirah; Daud, Abdul Razak; Jalar, Azman
    Investigation of inorganic (silica) and organic (lignocellulose) compounds extract from paddy (Oryza Sativa sp.) waste as corrosion inhibitor for carbon steel was studied in acidic medium. Silica was obtained by the burning process of rice husk using muffle furnace at high temperature meanwhile, lignocelluloses compound was yield via chemical process of the rice straw. Optical Microscopy, XRD, FTIR, SEM and TEM were used to characterize of both samples. Corrosion test via weight loss method was performed at room temperature in different time interval and varied concentration in ppm of silicate and lignocellulose solutions. Results show that the corrosion inhibition efficiency was found to be increased with increasing concentrations of both corrosion inhibitors.
