| Abstract: | Biosorption equilibrium and kinetics of reactive black 31 from aqueous solutions by waste beer yeast sludge was investigated.The interaction between functional groups of waste beer yeast sludge and reactive black 31 was studied by the aid of Fourier infrared spectroscopy analysis.Results showed that the biosorption of reactive black 31 by waste beer yeast sludge was easy.Biosorption was quick before 20min,afterwards slowed down until the equilibrium time of 2h.The biosorption kinetics data could be describe... |
