| Abstract: | Acridine, p-amino benzaldehyde and diethanol amine have been shown to exhibit increasing inhibition efficiencies with concentration of the respective inhibitors. The temperature coefficient of inhibition was found to be negative for all the three inhibitors and the activation energy for the process in-creased on addition of inhibitors. All these compounds follow both Langmuir and Freundlich adsorption isotherms. The heat of adsorption obtained by Langmuir equation indicated the adsorption to be of physical in nature. The negative free energy and the entropy of adsorption were higher for acridine and p-amino benzaldehyde than that for diethanol· amine which explained the better performance shown by acridine and p-amino benzaldehyde in protecting carbon steel in citric acid in comparison to that of diethanol amine. |
