Abstract The effect of Cl- ion on the anodic dissolution of iron in H2SO4 solutions containing low H2S levle has been stdied by electrochemical polarization curve measurements.Meanwhile,the stable adsorption patterns of Cl- and HS- ions on iron surface were determined with CNDO/2 method.Furthermore,the total energy and binding energy of the competitive adsorption between Cl- and HS- ions under the anodic potential as well as the net charge distribution of iron atoms were calculated.The results showed that certain concentration of Cl- ion could adsorb steadily in the anodic regions of electrode surface,reduce the interfacial concentration of HS- ion,and thereby inhibit the anodic reaction of iron.However,when Cl- ions reached saturated adsorption,the reaction courses changed into iron dissoltion promoted by Fe(Cl-)ads.The critical concentration of Cl- ion for the action transition was 1 mol/L

Key words: iron anodic dissolution Cl- H2S CNDO/2
