Resumo

The present work aims to study the possibility of zinc, cadmium and manganese removal from synthetic solutions simulating wastewater from washing soil by electrocoagulation process using stainless steel mesh electrodes.The influences of current density (from 10 to 40 mA cm-2), time (20 and 40 minutes) and pH (4 to 10) on removal efficiency were explored in a batch cell to determine the best experimental conditions. Under the operating conditions tested, the best result was observed at pH = 10, corresponding to about 90% of heavy metals removal from solutions initially containing 15 mg dm-3 of each metal, with a power consumption of 9 kW h m-3.There are few published studies using stainless steel electrodes for the treatment of mixed heavy metals and this study newly indicated that the proposed method is adequate to remove the common heavy metals found in wastewater from heavy metals polluted soil.
