Abstract:
Two locally available, cost-effective, renewable biosorbents including the untreated straw of Smyrniopsis Aucheri and untreated leaf of Acer Negundo were used for the removal of Methylene Blue dye. The influence of initial dye concentration on the dye removal was investigated. Isotherm and kinetics of the biosorption process were studied. The optimum pH was found to be 6 and 5 for Smyrniopsis Aucheri and Acer Negundo, respectively. The optimum biosorbent dosage was found to be 0.3 g for Smyrniopsis Aucheri and 0.5 g for Acer Negundo. The removal of Methylene Blue by Smyrniopsis Aucheri and Acer Negundo occurred during 10 and 15 min, respectively. The quick biosorption using reasonably small amount of such natural and untreated materials is a big advantages of this work for wastewater treatment applications in an environmental friendly way. The Langmuir adsorption isotherm model, was found to be the best applicable one to fit the experimental data. The pseudo-second and pseudo-first order kinetic models were applied well to describe the kinetics of Smyrniopsis Aucheri and Acer Negundo biosorption, respectively.
