【摘要】 以童亭煤重质组族组分为原料，KOH为活化剂，制备了高比表面积活性炭，研究了碱炭比对活性炭孔结构及其吸附亚甲基蓝和苯酚性能的影响。结果表明，活性炭AC-4有最大的比表面积(3 752 m~2/g),对2 000 mg/L的亚甲基蓝溶液吸附量达到最大，为1 996.74 mg/g,吸附率高达99.84%;而活性炭AC-2对120 mg/L的苯酚溶液吸附量达到最大，为107.08 mg/g,吸附率高达89.23%。活性炭对亚甲基蓝和苯酚有不同的吸附机制，对亚甲基蓝的吸附以孔隙填充为主，而对苯酚的吸附则以π-π相互作用为主。更多还原

【Abstract】 High surface area activated carbons were prepared using the heavy components(HC) from Tongting coal as the raw material and KOH as the activating agent.The effects of the KOH/HC mass ratios on the pore structure of the activated carbon and its adsorption performance towards methylene blue and phenol were investigated.The results show that the activated carbon AC-4 exhibites the highest specific surface area of 3 752 m~2/g and a maximum adsorption capacity of 1 996.74 mg/g with a remarkable adsorption rate of 99.84% for a MB solution with an initial concentration of 2 000 mg/L.In contrast, the activated carbon AC-2 demonstrates a maximum adsorption capacity of 107.08 mg/g with a high adsorption rate of 89.23% for a phenol solution with an initial concentration of 120 mg/L.The activated carbon has different adsorption mechanisms for methylene blue and phenol.The adsorption of methylene blue is primarily attributed to pore filling, whereas the adsorption of phenol is mainly governed by π-π interactions.更多还原
