tailieunhanh - Removal of heavy metals derived from COD analysis wastewater by electrolysis using graphite electrode

The results showed that the electrolysis process was not affected by the electrode’s distance or area. The most efficient treatment for all three metals was achieved at a current value of mA, which corresponds to a current density of mA/cm2 under a voltage of 3 V, 8-h electrolysis time, wastewater pH |
