dc.description.abstract	Lignin is one of the most abundant natural polymers on earth. Malaysia is the largest producer of oil palm and thus can produce huge amounts of lignin from its lignocellulosic waste. One of the applications of lignin could be corrosion inhibitor. Initial corrosion studies have shown good inhibition where inhibitor efficiency (%IE) was 90 and 87% for pH 6, and 90% for pH 8 at the highest concentrations of native soda lignin (SL) and Kraft lignin (KL) respectively on mild steel in 3.5% NaCL solutions. The inhibitive efficiencies increased with the increase in concentrations of SL and KL. Both SL and KL were found to act as mixed type inhibitors. Both lignins can adsorb onto the metal surface physically and then react chemically with iron ions to form a protective film that hinders further corroding process. Electrochemical tests were performed on three lignin monomers namely p-cumaric acid (CA), ferulic acid (FA) and hydroxybenzaldehyde (HB) on mild steel.	en_US
