Abstract

Corrosion inhibition of aluminium in 0.5M 𝐻 􀀀􀀁􀀂 by methanol root extracts of Petiveria alliacea was investigated by weight loss and linear polarization techniques. The weight loss is concentration dependent and increases with increasing concentration of Petiveria alliacea root extracts (PARE). The inhibitor (PARE) exhibited highest inhibition efficiency of 75.28% at the highest inhibitor concentration of 8g investigated. Inhibition was found to increase with increasing PARE concentration. PARE showed molecular adsorption of phytochemicals present as active ingredients through the hetero atoms in their molecules. Polarization studies showed that the extracts act as a mixed type inhibitor. The inhibitor obeyed the Langmuir adsorption isotherm equation.
