Abstract

The inhibitive effect of compound inhibitor including emulsifier(P)、zinc sulfate、sodium polyphosphate、Glucose Gluconate was studied in 31% NaCl(bymass) solution.The inhibitory mechanism was analyzed by polarization curve and EIS.The results showed that the compound inhibitor was anodic-type inhibitor and its inhibitive effect on anodic and cathodal reaction was the most obvious at 200×10-6g·L-1.And the results of EIS revealed that the inhibition efficiency increased and the film formed on electrode surface was more and more compact with time.Inhibition mechanism was different with concentration of inhibitor.
