Abstract
THERMODYNAMIC PROPERTIES OF SALICYLIC ACID AS CORROSION INHIBITOR OF CARBON STEEL IN HYDROCHLORIC ACID PICKLING ENVIRONMENT
Boshra Ahmed Abazid*, Deeb Bakir and Mohammad Ali Al-Shekh
ABSTRACT
The corrosion inhibition of carbon steel in 0.1 M HCl by salicylic acid (SA) was investigated using weight loss method in the temperature range of 313-343 K. It was found that the inhibition efficiency increases with an increase in (SA) concentration but decreases with an increase in temperature. It has been determined that the adsorption for the studied inhibitor on carbon steel complies with the Langmuir adsorption isotherm at all studied temperatures. Both kinetic parameters (activation energy, pre-exponential factor, enthalpy of activation and entropy of activation) and thermodynamics of adsorption (enthalpy of adsorption, entropy of adsorption and Gibbs free energy) were calculated and discussed.
