Abstract: Corrosion inhibition effect of Anthocleista djalonensis on mild steel was studied using gravimetric method for 1.0 M of HCl at different temperatures – ambient and 333K. The mild steel were immersed in the uninhibited corrosive media and those containing 0.1 g/l, 0.2 g/l, 0.3 g/l, 0.4 g/l, 0.5 g/l and 0.6 g/l of the extract for both the ambient temperature and 333K. The inhibition efficiency of the extract was determined, after weight losses were calculated and optimum value was gotten as 97.23% for ambient and 84.62% for 333K. The adsorption studies revealed Langmuir isotherm as the best model for the isotherm (r2=0.9998 for ambient temperature and r2=0.9966 for 333K) on the mild steel surface. This shows that Anthoclesista djalonensis is a good green inhibitor, obeying the strict environmental legislations for the “green” alternative of mitigating corrosion.
