Abstract

This paper focus on the adsorption of methylene blue (MB) in aqueous solution on carbon prepared from soybean residue (TBĐ). The experiments were conducted using the following parameters: TBĐ mass is 0.05g/25 mL, shaking speed is 200 rounds/minute, equilibrium time is 90 minutes at room temperature (25±1⁰C); pH is best 8. Mass TBĐ needed for MB adsorption is best at 0.05 g/25mL of MB solution. In the temperature range of 298 - 323K, the values of ΔG^o < 0; ΔH^o = -18.3 kJ/mol implicates that the process is self-inflicted and exothermic. The result indicates that, maximum adsorption capacity was calculat by the Langmuir adsorption isotherm model as 166.67 mg/g at 298K.
