Abstract
The effect of Citrus reticulata extracts on the corrosion of copper in 1M NaOH solution was
studied using weight loss method at various temperatures varying from 298 to 328 K. Experimental data
revealed that Citrus reticulata extract acted as an inhibitor in the alkaline environment. It was found that
the inhibition efficiency increased with an increase in Citrus reticulata extract concentration. Adsorption
enthalpies were determined and discussed. Effect of temperature was also investigated and activation
parameters were evaluated.
