... = 4.5) at 25°C. Linear polarization resistance (LPR) measurements were conducted to determine the corrosion rate (CR) over a wide range of CI concentrations, from which surface saturation concentration and surface coverage values were extracted. Kinetic parameters for adsorption (kA, kD, and KAD) were...
