摘要:Sugarcane bagasse-based activated carbon which has high adsorption capacity of color in icroporous and mesoporous size in solution phase was produced through combination of hydrothermal carbonization (HTC) and chemical activation processes using phosphoric acid asan activating agent.The activated carbon which was obtained from HTC process at 250° C for 9 hours,followed by chemical activation process at 750° C for 90 minutes with animpregnationratio of 10%(weightratio of phosphoric acidto hydrochar) has a BET surface area of 903.47 m2/g,a total pore volume of 0.597 cm3/g (volume composition: 63.32% of micropores and 36.68 % of meso-macropores),an iodine number of 951.99 mg/g,and a methylene blue number of 170.40 mg/g.The FTIR analysisindicatedthe presence of an aromatic group and a polarity character inthe activated carbon produced.The XRD analysis revealedthat the activated carbon hadhexagonal crystallite and mesoporous surface structures.The SEM analysis showed that the surface topography of the activated carbon had an average pore diameter between 3-10 μm.
