Abstract
Chloride ion migration and the choice of optimized current density during galvanostatic dechlorination of simulated cast iron artifacts in alkaline solution were studied by means of galvanostatic polarization. The results showed that the more treatment time and the more current density, the more was the extraction ratio of chloride ion and the less was the electrical efficiency. The current density was optimized with respect to the extraction ratio of chloride ion and the electrical efficiency, and the optional current density was presented.
