Abstract | Electrolysis of water produces hydroxyl radical at anode in the electrochemical reactor. In this study, anode and cathode materials were made of titanium/platinum/ruthenium (Ti/Pt/Ru) and titanium (Ti) respectively. Several series of batch experiments were conducted to study the hydroxyl radical monitoring in electrochemical oxidation. Experimental active time was lasted for 120 minutes, using 200 ml volume of reactor. Para-chlorinated benzoic acid (pCBA) was used as chemical probes to measure the formation of hydroxyl radical. At optimum hydroxyl radical formation condition, synthetic dye wastewater was treated in this reactor. Batch experiments were conducted at 500ml volume and the operation time lasted for 180 minutes. Wastewater treatment, using produced hydroxyl radical was proved effective for color and COD removals. Removal efficiency of color was 90% for NaCl and 65% for KH2P04 while COD removal efficiency was 80% and 10% respectively. Anodic current efficiency was 26.98(kg-COD/ A/h./m2 ) for NaCl and 0. 79(kg-COD/ A/h/m2 ) for KH2P04.which shows higher value than in the literature 0.75(kg-COD/A/h/m2 ) . |
