| 英文摘要 | In this study the adsorption of New Methylene blue (Basic blue 24) on sawdust of Malus domestica was investigated. The sawdust was chemically treated to enhance the adsorption capacity. Adsorption experiments were performed at different temperatures ranging from 20-40 degrees C on both raw and treated sawdust samples. The residual concentration of the dye was determined by UV-Vis spectrophotometric technique. Effect of various reaction parameters like temperature, initial dye concentration, equilibration time and pH was studied. Sawdust was characterized by BET, FTIR, Scanning electron microscopy (SEM), and Energy dispersive spectroscopy (EDS) techniques. Adsorption kinetics was interpreted using intra particle diffusion and Bangham models and both models were found to best describe the sorption of New Methylene blue onto M. domestica. Thermodynamic parameters like Delta E degrees, Delta H degrees, Delta S degrees and Delta G degrees were calculated from the adsorption kinetics data. The data show that the adsorption is an endothermic process. The negative value of entropy shows that the dye molecules take an oriented position on the adsorbent surface. Adsorption data fitted well with Langmuir, Freundlich and Temkin adsorption isotherms. All results clarify that M. domestica sawdust is a useful cheap adsorbent for removing basic dyes. |
