The eco-friendly inhibitor is used to safeguard the environment as well as the industrial equipments where corrosive acids are used for cleaning purposes. The inhibition ability of Atalantia monophylla leaves (AML) on the deterioration of mild steel (MS) in acid medium was investigated by mass loss and electrochemical techniques. The inhibition capability raised with rising the concentration of AML extract from weight loss method, immersion period and temperature studies. Electrochemical studies data explained in which AML inhibitor performed like cathodic and anodic type of inhibitor in corrosive medium. The adsorbed layer formed on the metal due to AML extract fulfilled the Langmuir adsorption isotherm. The formation of the protective film on the MS surface was acknowledged by SEM, EDS and FTIR. All the techniques proved AML as acceptable corrosion inhibitor in 1N HCl medium.
