Abstract
The corrosion protection of mild steel in 1 M H3PO4 solution by apricot juice was studied at different temperatures by weight loss technique. Adsorption, activation and statistical studies were addressed in this work. Adsorption studies showed that inhibitor adsorbed on metal surface according to Langmuir isotherm. Average value of heat of adsorption was −14.93 kJ/mol indicates a spontaneous physical adsorption on metal surface. Activation parameters did not changed with addition of inhibitor indicates that there is no change in reaction mechanism. Analysis of variance (ANOVA) was also applied. This analysis showed that the corrosion rate influenced by temperature, inhibitor concentration and combined interaction of them.
