摘要:The present work presents the results obtained during the treatment of a syntheticaqueous solution contaminated by zinc or iron at the laboratory scale byelectrocoagulation process. Iron and aluminum electrodes are used separately. Theinfluence of the electrocoagulation parameters as well as the pH of the liquid have beenstudied. In order to understand the process of EC, natural decanting was done after EC.The treatment with the iron and aluminum plates with a voltage of 1.5V and a currentdensity of 1.5 A.m-2 allowed a heavy metal removal after 5 hours of settling. It wasfound that the treatment duration, the settling time and the pH of the medium play amajor role in the treatment by electrocoagulation. The treatment with Aluminumelectrode allowed 54.47% and 100% removal of Zinc and iron respectively whereasiron electrode allowed 40.65% and 100% removal of zinc and iron respectively. Thetreatment with aluminum electrode allows fast removal of the two heavy metals insolution. Treatment with aluminum blades seems to be more effective than iron blades.
