摘　　要：采用酸、碱对煤基活性炭进行表面改性,并以自制吸附装置考察室温下改性前后的活性炭对四氯化碳、苯的吸附能力。结果表明:经酸、碱改性的活性炭对四氯化碳的吸附能力都有所提高,但对苯的吸附性能没有明显改善;用浓度为0.676 2mol/L的硝酸溶液12.5mL酸改性活性炭可用于处理含Pb2+废水。Coal-based activated carbon was modified using nitric acid and sodium hydroxide, the adsorption performance to tetrachloride and benzene was evaluated by home-made adsorption apparatus. The results show that the modified activated carbon shows obvious improvement for adsorpting tetrachloride, but no significant influence for adsorpting benzene compared with that without treatment. The activated carbon modified by nitric acid can be used to treat simulated lead- bearing wastewater.
