An experimental study of iron corrosion in sulfuric acid solution containing inhibitors by noise measurement

The corrosion of pure iron was studied by electrochemical noise potential measurements in 0.5 mol/dm exp 3 H sub 2 SO containing dibenzyl sulfoxide and plenyl thiourea, respectively, as the inhibitor. The corrosion current density was found to be inversely proportional to the mean square of the pote...

Summary:The corrosion of pure iron was studied by electrochemical noise potential measurements in 0.5 mol/dm exp 3 H sub 2 SO containing dibenzyl sulfoxide and plenyl thiourea, respectively, as the inhibitor. The corrosion current density was found to be inversely proportional to the mean square of the potential noise. The proportionality constant was determined with solution anlaysis and harmonic analysis.
