In this work, the performance of batch electrocoagulation (EC) treatment using iron electrodes with monopolar configuration for trivalent chromium (Cr3+) removal from a synthetic wastewater was investigated. The influences of current density (from 2 to 25 mA/cm2) and initial metal concentration (from 50 to 250 mg/L) on the removal efficiency were explored in a batch stirred cell to determine the best experimental conditions.
