The aqueous extract synthesized using the biomass, Ziziphus spina-christi, was applied to protect the surface of aluminium under acidic environment. The influence of extract concentration (0-0.14 mg/ml), contact time (2-8 h) and temperature (303.15-313.15 K) on the inhibition efficiency was studied. Langmuir isotherm fitted well to the experimental observations (R2 0.96 confirmed the monolayer attachment of inhibitors. The values of activation energy observed in this study suggests that the inhibition process to be surface inte
