Electrochemical degradation of reactive orange 16 by using charcoal-based metallic composite electrodes

The performance of charcoal composite electrodes, by using commercial activated charcoal and charcoals from coconut trunk, mangrove wood, rubber wood, and sugarcane, was compared in an attempt to fabricate effective and low cost electrodes for wastewater treatment in textile industries. Reactive Ora...

The electrode efficiencies were determined based on the percentage of Reactive Orange 16 decolourisation. The charcoals used, duration of electrolysis, functional groups present in charcoals, Brunauer-Emmett-Teller surface area and production of hypochlorite ion that contribute to the effectiveness of the electrodes were examined.
