| Abstract: |
| In order to explore the decoloration efficiencies of modified bagasse for dyeing wastewater,aqueous solutions of Congo Red and Methylene Blue were taken as simulated wastewater to investigate the decoloration efficiencies by DMDAAC-Mg2+ modified bagasse under different conditions, such as the modified bagasse dosage, pH, contact time,initial concentration of dye and temperature. The results demonstrate that the DMDAAC-Mg2+ modified bagasse shows favorable decoloration efficiencies on both Congo Red and Methylene Blue.Themodified bagasse dosage, pH and contact time are the main factors which affect the decoloration efficiency. The orthogonal tests indicate that the maximum decoloration efficiencies can reach 97.96% and 91.89% for Congo Red and Methylene Blue, respectively. Under the same experiment condition, DMDAAC-Mg2+ modified bagasse exhibits the highest decoloration efficiency comparing with single factor modified bagasse and raw material. |
