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.
In this research the electroplating method of chromium was used on
iron ore (steel), it is one of the coating methods for the formation of
a roof cover using chromium (III) chloride salts as a source of
chromium and sulfuric acid as a catalyst.
