Inhibition efficiency increases with increase in inhibitor concentration but decrease with rise in temperature. Maximum inhibitor efficiency was around 90%. The adsorption behavior of Ziziyphus leaves extract obeyed the Langmuir adsorption isotherm while the effect of temperature was according to Arrhenius Model. ER -
