Abstract :
The anti-corrosive activity of chitosan (CT) on
mild steel in HCl solutions was determined using
gravimetric and electrochemical methods such linear
polarization resistance (LPR), electrochemical impedance
spectroscopy (EIS) and potentiodynamic polarization
(PDP) methods. The gravimetric measurements indicated
that the inhibition efficiencies of CT 47.62 - 64.25%. The
LPR results gave the experimental inhibition efficiency of
CT to be 67.46-97.85 % while potentiodynamic polarization
resistant method was 56.19 - 89.09%. The EIS
measurements indicated 78.45 - 90.96 % as an inhibition
efficiencies of CT.
