Evaluation of Dryopteris cochleata leaf extracts as green inhibitor for corrosion of aluminium in 1 M H2SO4
Corrosion inhibition of aluminium in 1 M H2SO4 by two different solvent extracts of Dryopteris cochleata leaves was studied using weight loss, electrochemical measurements, X-ray diffraction and scanning electron microscopy.

| Summary: | Corrosion inhibition of aluminium in 1 M H2SO4 by two different solvent extracts of Dryopteris cochleata leaves was studied using weight loss, electrochemical measurements, X-ray diffraction and scanning electron microscopy. Characterization of plant extract was carried out using Fourier transform infrared spectroscopy. X-ray diffraction and SEM analysis have confirmed the molecular adsorption of the DCLME and DCLWE extracts on the aluminium surface. The methanol extract of D. cochleata leaves is a better inhibitor than water extract. Polarization studies showed that the extracts act as a mixed type inhibitor. |
