Removal Mechanisms of Acid Dyes of Different Chemical Groups under Anaerobic Mixed Culture

S. Wijetunga, L. Xiufen, R. Wenquan, J. Chen


Removal mechanisms of Acid Red 131, Acid Yellow 79 and Acid Blue 204 dyes with different chemical groups under anaerobic process using mixed anaerobic granular sludge were studied. The UV-visible spectrum obtained and dissolved residual chemical oxygen demand measured at the end of incubation suggest that Acid Red 131 and Acid Yellow 79 were biodegraded and no further degradation of dye metabolites have occurred. Acid Red 131 and Acid Yellow 79 were decolourized by biodegradation achieving 81% and 97% of colour removal at 300 mgl-1 dye concentrations, respectively. Acid Red 131 biodegradation followed the first order kinetic model with respect to dye concentration while Acid Yellow 79 biodegradation followed the second order kinetic model. Although over 90% of colour was removed in Acid Blue 204 dye, no biodegradation was noticed. It is clear that different dyes can be decolourized under anaerobic condition even though mechanism of decolourization is not same.
