Study on the electrochemical performance of aluminum anode based on polarization curve method
The electrocoagulation technology has advantages such as high efficiency, no need for adding chemicals, no secondary pollution, simple operation and equipment maintenance. However, there are issues such as unclear electrochemical performance patterns of the electrode plates. This article used polarization curve method to study the electrochemical performance of sacrificial anodes, and carried out experimental researches on the influences of different initial salt mass concentrations, pH, and oil mass concentrations on the electrochemical performance of sacrificial anodes. The results showed that the passivation current density increased, the potential range of the anode passivation zone narrowed, and the dissolution rate of the anode surface increased with the inceasing mass concentration of sodiur chloride solution; when the initial pH was too small or too large, the anodic dissolution rate increased, and the destruction of passivation film was enhanced; the increase in initial oil mass concentrations had little effect on the electrochemical properties of the aluminum anode and did not affect the dissolution rate of the anode. The research conclusion provides a theoretical basis and scientific basis for the application of electrocoagulation technology in emergency response to marine oil spills.
