INHIBITION POTENTIAL OF PLANT EXTRACT OF POLYCARPAEA CORYMBOSA
Keywords:
Mild steel , EDS ,Polycarpaea Corymbosa (PC)Abstract
Adsorption and thermodynamics study of the inhibition of corrosion of mild steel in 1 M HCl medium using the plant extracts Polycarpaea Corymbosa (PC) was carried out. The inhibitive and adsorptive properties of ethanol extract of PC was investigated using weight loss technique by varying concentration inhibitor at two different temperatures. The adsorption behavior of the plant extracts on mild steel specimen was analyzed using Langumuir and Tempkin isotherm. The elemental analysis and pattern of adsorption of the inhibitors molecules to the metal surface were visualized through EDS studies. In addition, the phytochemical screening and biological activity were evaluated.
