摘　　要：采用正交试验方法,以生物质海绵-丝瓜络纤维为原料、(NH4)2HPO4作为活化剂制备活性炭纤维(ACF)。制备过程包括预处理、预氧化、高温活化。采用扫描电镜(SEM)对制备的活性炭纤维结构进行表征分析。通过N2吸附-脱附等温曲线对其表面孔结构进行研究。结果表明:制备的丝瓜络海绵基活性炭纤维比表面积达到812.7m2/g,孔隙结构主要为微孔结构,孔体积可达0.390cm3/g,在环保等领域具备良好的应用前景。The preparation of activated carbon fiber based on luffa sponge fibers（LSF-ACFs） was studied.Orthogonal test had been employed to analyse the function of（NH4）2HPO4 as the activating agent.The process included pretreatment,pre-oxidation and activation.Scanning electron microscopy（SEM） was applied to characterize its morphology.Nitrogen adsorption-desorption isotherms were applied to characterize its surface pore texture.The reseach results indicated that the BET surface area of LSF-ACF prepared in experiments presented the biggest of 812.7 m^2/g,abundant micropores were observed,and the pore volume reached 0.390 cm^3/g.The activated carbon fibers produced from luffa sponge fibers showed a promising application prospect.
