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.
