摘要

Abstract

Changes in electrochemical parameters and inhibition performance with inhibitor concentration were investigated by electrochemical measurements of propargyl derivative inhibitors in acidic solution. It was found that with increasing inhibitor concentrations

double layer capacitances

polarization resistances and inhibiting efficiencies showed extreme behavior at certain inhibitor concentration in sulfuric acid but not in hydrochloric acid medium. Analysis of the changes in desorption and corrosion potentials with inhibitor concentration showed that this extreme phenomenon resulted from inhibitor desorption occurring at around corrosion potential in sulfuric acid solution as the inhibitor concentration reached this certain value.
