Different aeration periods (3. h in phase 1 and 2; 3, 6 and 15. h in phase 3; 24. h in phase 4 and 5) in aerobic chamber were studied with different MO concentration 50, 100, 200, 200 and 300. mg/L as influent from phase 1-5. The color removals estimated from the standard curve of dye versus optical density at its maximum absorption wavelength were 97%, 96%, 97%, 97%, and 96% and COD removals were 75%, 72%, 63%, 81%, and 73% in phase 1-5, respectively. The MO decolorization and COD degradation followed first-order kinetic model and second-order kinetic model, respectively. GC-MS analysis indicated the symmetrical cleavage of azo bond and the reduction in aromatic peak ensured the partial mineralization of MO. 2014-05-23T08:48:43Z 2014-05-23T08:48:43Z 2013-09 Article Bioresource Technology, vol. 143, 2013, pages 104-111 0960-8524 http://www.sciencedirect.com/science/article/pii/S0960852413009127 http://dspace.unimap.edu.my:80/dspace/handle/123456789/34697 en Elsevier Ltd.
