| dc.description.abstract | The electrocoagulation (EC) is an electrical process include destabilizing suspending solids, emulsion or solved pollutants in aqueous solutions by using electrical currents. In this study, zinc and iron based of metal wastes are used as electrode to reduce purchasing cost of commercial electrode since this treatment consumed electrical energy to supply electricity leads to high operating cost. The size of electrolysis cell was 1.1L which fitted with a pair of electrodes represent anode and cathode. The parameter involved in this study are current density (5-30 mA/cm2), initial concentration (25-100 ppm) and electrolysis time (10-50 min). The performance of removal is compared by percentage of colour removal and amount of dried sludge produced after the treatment process. Meanwhile, the optimum current density is 25 mA/cm2 gives efficiency of dye removal 95.73% for zinc and 92.93% for iron at 30 minutes of treatment process. For both electrodes, it was found that the removal efficiencies will be reduced as the initial concentration increased. For reaction time, the optimum duration of treatment process for both zinc and iron electrodes is 30 minutes with efficiencies 95.73% and 92.93% respectively. The performance of zinc electrode in colour removal was found to be better than iron electrode owing to its treated water produced was clear and odourless instead of iron produced yellowish and greenish which interrupted the water quality. | en_US |
