摘要：

The inhibition of carbon steel corrosion by lignin in two different acid solutions, 1 M HCl and 1 M H2SO4 have been investigated via weight loss methods in varying temperatures of 40, 50 and 60 degrees C. With the addition of lignin, carbon steel showed less corrosion attack in HCl medium compared to H2SO4. The use of lignin showed the different inhibition effect in varying temperature especially in H2SO4. The influence of anion in both acid solutions, temperature and the dependency of lignin concentration were discussed.
