Evaluation of the inhibition efficiency of Pogonatum microstomum for mild steel in acid medium using gravimetric, kinetics, electrochemical studies and statistical modeling
Electrochemical studies; Mild steel; Pogonatum microstomum; Statistical modelling
Mosses from a distinct lineage of bryophyte family are found as thick green carpet on the moist rocks, trees, soil or streams. It is acclaimed for its good antimicrobial properties and is a reservoir of various phytochemicals. The nontoxicity nature and abundant availability in nature was exploited for the first time to investigate its effectiveness as novel and green corrosion. Present study deals with the evaluation of corrosion inhibition efficiency of the moss, Pogonatum microstomum using the electrochemical studies and weight loss studies. The moss extract showed a maximum corrosion inhibition efficiency of 95.28 % for 3hrs of immersion period at 303 K. Increase in the inhibition efficiency with concentration of moss extract is the result of adsorption of the constituents which are active on the surface of the metal. Tafel polarization and electrochemical impedance studies gave results on par with the weight loss measurements. The experimental results obtained were further validated by statistical analysis and statistical modeling using SPSS 20 software. 2020 American Institute of Physics Inc.. All rights reserved.
