BIOCHAR PRODUCED FROM ANAEROBICALLY DIGESTED SUGARCANE BAGASSE: STRUCTURAL MOPHORLOGY CHARACTERIZATIONS AND APPLICATION TO REMOVE NIKEL CONTAMINANTED WAST WATER
In this study, biochar (BC) successfully produced by anaerobic heating the derived bagasse. Structural mophorlogy characteristics of the obtained materials were investigated by scanning electron microscopy methods (SEM), X-ray energy scattering spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR). SEM images show that the fabrication materials have a large specific surface, porous structure. EDS spectroscopic results show a significant change in BC's elemental composition compared to the original material. FTIR spectra indicated that the fabricated materials contain surface functional groups such as -OH, -COO, = C = O, ... Test of domestic nickel separation ability of BC material samples obtained efficiency high adsorption (90.55%) with saturated adsorption time at 35 minutes. The results of our study show that BC material made from bagasse has great potential in application of heavy metal treatment in water.
