Abstract


Adsorption via activated carbon (AC) is one of the superior treatments for stabilized landfill leachate, but expensive and limited resource of AC precursor (bituminous and lignite) limit application of this technique in landfill leachate treatment. Based on previous studies, agriculture waste performed as an excellence potential for AC precursor. Thus, present study evaluates the sugarcane bagasse derived activated carbon (SBAC) for adsorptive removal of ammonical nitrogen, COD, and color from old anaerobic landfill leachate located in Perak, Malaysia. The chemical and physical properties of adsorbent were examined by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM). The effects of AC dosage (g) on adsorption performance were investigated in a batch mode study. Equilibrium data were favorably described by Langmuir isotherm model, with a maximum monolayer adsorption capacity for NH3- N, COD and color at 14.62 mg/g, 126.58 mg/g and 555.56 Pt/Co, respectively. The results illustrated the potential usability of SBAC for treatment of anaerobic landfill leachate.
