Physico-chemically activated coconut shell-based carbon electrode was fabricated to treat anthraquinone dye. Electrode was moulded using specific solvent according to following formula : 54% activated carbon (100 or 200 mesh), 43.3% water, and 2.7% polyvinyl alcohol. Performance of electrode was investigated based on UV-Vis spectra data of RB19 dye degradation on varied carbon particle size (100 and 200 mesh), type and concentration of electrolyte (NaCL and Na2SO4), applied potential (5, 6, 7 V), and electrode doping (PbO2 and B). The absorbance peak at λ590 and λ226 was decreased for 67-75% and 38-42%, respectively, using fabricated electrode. Type and concentration of electrolyte as well as applied potentials were not related to the increasing of efficiency of degradation process. PbO2 and Boron doping showed conflicting behaviors;boron-doping was able to increase the performance of electrode, but on the other hand, PbO2 doping shows no effect.
