Color removal efficiencies approaching 94, 90 and 96% were obtained with influent MO concentrations of 50, 100 and 150 mg l-1 respectively. COD removal decreased with respect to the increasing of color concentration. Maximum COD removal was attained 69% in 50 mg l-1 of MO. Cleavages of azo bond tends to the accumulation of aromatic amines which contributed COD in the effluent. Zero-, first-, and second-order reaction kinetics were used to find out the suitable COD removal and decolorization kinetics. The COD removal process was suitable to second-order reaction kinetic, and the degradation of MO approximates was suitable to the first-order kinetic model. The regression coefficient (R2) for both decolorization and COD degradation was around 0.9 which ensures the high-degree linear relationship between the concentration and time. 2014-05-22T14:58:28Z 2014-05-22T14:58:28Z 2013 Article Desalination and Water Treatment, vol. 51(40-42), 2013, pages 7621-7630 1944-3986 http://www.tandfonline.com/doi/abs/10.1080/19443994.2013.782255#.U34NpNKSygY http://dspace.unimap.edu.my:80/dspace/handle/123456789/34660 en Taylor & Francis
