Corrosion inhibition effect of Chlorhexidine in 1M sulfuric acid with concentration range from 10 -500 ppm have been investigated on mild steel substrate by weight Loss, Open Circuit Potential and Potentiodynamic Polarization techniques. Shifting of Open Circuit Potential curves towards the positive direction with increasing the inhibitor concentrations, indicates the adsorption of inhibitor molecules on the surface of mild steel, consequently this lead to the corrosion mitigation. Chlorhexidine shows its best inhibition performance with 500 ppm solution. The result obtained by Potentiodynamic Polarization method is in good agreement with the weight Loss method. From the polarization parameters it is revealed that inhibitor is of mixed type of inhibitor. The surface analysis has been done by Scanning Electron Microscopy. This inhibitor obeys the Langmuir’s adsorption isotherm phenomenon.
