dc.description.abstractHerein, a chemically activated carbon (AC) has been prepared from molasses-to-ethanol-process waste (vinasse). The procedure involves the preparation of carbonaceous spheres (CS) from the hydrothermal carbonization of the vinasse followed by activation with KOH at 800 degrees C. The effects of sole thermal treatment (without KOH) and the chemical activation on the structure and morphology of CS were evaluated by means of TGA, FT-IR, XPS, Raman spectroscopy, SEM and BET techniques. The sole thermal treatment produced a carbonaceous material with equal micro-mesoporous contents and a specific surface area (189 m(2)/g). On the other hand, the KOH-based activation produced a mainly microporous AC (V-micro = 0.574 cm(3)/g, V-total = 0.691 cm(3)/g, V-micro/V-total = 0.83) with a high specific surface area (1042 m(2)/g). Batch adsorption efficiency of AC was determined by using Victoria Blue B as a model dye in aqueous solution as functions of several operation parameters. Based on the non-linear regression analysis, the Langmuir isotherm model with monolayer adsorption capacity of 713.254 mg/g was preferable. The obtained AC was reusable for at least five cycles of adsorption-desorption. All results showed that the prepared AC has potential usability for the treatment of water polluted by dye-stuffs.
