Abstract

The corrosion behaviour of iron in four different organic acid have been investigated using weight loss method. The acids used includes succinic, formic, maleic and citric acid. The results of the corrosion rates of iron in C4H4O4, C4H6O4, HCOOH and C6H8O7 are 1.125, 1.100, 0.800 and 0.500 mg cm-2h-1 respectively. The rate of corrosion increases with increasing concentration of acid and with increase in temperature. The study shows that the rate of corrosion follows the order of reactivity C4H4O4 > C4H6O4 > HCOOH > C6H8O7.
