have been studied using weight loss and thermometric methods at 303
and 333K. Results show that the exudates gums actually reduced the rates of
corrosion of mild steel. Increase in the concentrations of the exudates gums
increased their percentage inhibition efficiencies. Corrosion rate was found
to increase with increase in temperature in the presence and absence of the
gum exudates, though the corrosion rate was slower in the presence of the
exudates gums. Both DO and CA exudates gums were found to obey Temkin
and Langmuir adsorption models at all concentrations and temperatures
studied. Physical adsorption mechanism was proposed from the adsorption
parameters. Kinetic and thermodynamic parameters revealed that the
adsorption process is spontaneous, exothermic and no significant difference
was found between the inhibition efficiencies of DO and CA.
