THE INHIBITION COEFFICIENT OF ADSORPTION INHIBITOR
Abstract:
The corrosion inhibition of quinoline, thiourea and benzyltriphenyl phosphonium bromide for carbon steel in acid medium have been investigated by weight loss method.The following relationship between inhibition coefficient γi (ratio of the corrosion velocity without inhibitor to that with inhibitor) and concentration of inhibitor (Ci) was found:logγi=αi+βilogCi. In the case of mixed inhibitor systems the over all inhibition coeffiieient γ:can be expressed as:logγ3=α3+β3log C1(concentration of the second inhibifor=constant) and logγ3=logγ1+blogγ2(b=β3/β1). When b>1, the inhibitors showed a synergistic inhibition effect.
