Rhizophora Apiculata As Eco-Friendly Inhibitor Against Mild Steel Corrosion in 1 M HCL

The inhibitive characteristics of aqueous extracts from mangrove (Rhizophora apiculata) bark and leaf on the corrosion of mild steel (MS) coupon in 1 M HCl were examined by means of the gravimetric measurement (weight loss), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarizati...
