摘要

Electrodialysis is an innovative process for wastewater treatment; in this study, it was used for the removal of chloride ions from a synthetic solution equivalent to acid mine drainage (AMD) generated from a hydrochloric acid leaching process. Electrodialysis removes ions through the application of an electric potential and the use of ion exchange membranes. Two anion exchange membranes (AXM-100S -Mem. International Inc.- and AEM Type II -Fujifilm Inc.-) were evaluated, along with variables such as current density (20–80 A/m2) and supporting electrolyte concentration (1–9 g/L NaNO₃), to assess the efficiency of this technique for chloride ion removal. Results showed that electrodialysis is suitable for wastewater treatment: at 50 A/m2 and 9 g/L NaNO₃, the AXM-100S membrane achieved a 92% removal efficiency, while at 80 A/m2 and 9 g/L, both membranes reached nearly 100% removal.
