摘要：
Electrochemical behavior of low carbon steel in a wide range of concentrations (0.05-1.00 M) of sodium gluconate and potassium tartrate were studied by potentiodynamic, potentiostatic and open-circuit measurements. The results showed that the rate of anodic iron dissolution was related to the concentration of the organic acid salt. The passivation behavior of low carbon steel was attributed to the formation of a layer of salt on the surface of the electrode. The result has been discussed on the basis of a dissolution-precipitation mechanism. By the addition of halide ions Cl-, Br-, and I- to the solution of organic acid salts, the anodic process of iron corrosion was stimulated.
