Abstract
           Many industries produce and discharge large quantities of dilute metal ion solutions from the acid treatment of alloys, electroplating rinses, and leaches and effluents from the manufacture of chemicals. This discharge is considered to be a serious environmental threat. Electrochemical treatment is used as a sustainable effective technology for removal of heavy metals. In this study, experiments were carried out using a bench-scale electrochemical cell incorporating flow-by porous graphite electrodes for deposition of iron. The effect of current density, feed flow rate, and initial iron concentration on removal efficiency and current efficiency were studied. Experimental results showed that the maximum removal efficiencies(99.7%) and (99.9%) were obtained at flow rate of 0.278 ml/s, for initial iron concentration of 100 ppm and 200 ppm respectively. For concentration of 50 ppm it was 99.48% at flow rate of 1.11 ml/s, current density of 0.98 mA/cm2 and pH of 4. and maximum current efficiencies were 53% at 100 ppm , 99.9% at 200 ppm ,at flow rate of 0.833 ml/s, and 38.05% at 50 ppm at flow rate of 1.11 ml/s all obtained  at current density of 0.98 mA/cm2. Solution pH in the range of 3 to 5 has a little effect on the deposition of iron.
