摘　　要：以活性炭纤维(ACF)为载体,制备了负载活性氧化铝(γ-Al2O3)的吸附材料(Al-ACF),利用SEM、FTIR对其进行表征分析,并探讨了氮磷在Al-ACF表面的吸附固定机制及γ-Al2O3晶体结构变化。ACF作为载体,有利于γ-Al2O3获得高分散度且增大其晶格缺陷程度,ACF与γ-Al2O3之间的协同作用也提高了Al-ACF脱氮除磷性能。Al-ACF脱氮除磷体系中以离子交换为主导,静电吸引和孔隙吸附也同时存在。An adsorbent(Al-ACF)loaded with activated alumina(γ-Al2O3)was prepared using activated carbon fiber(ACF)as carrier.It was characterized and analyzed by SEM and FTIR.The adsorption and fixation mechanism of nitrogen and phosphorus on the surface of Al-ACF and the change of crystal structure ofγ-Al2O3 were discussed.ACF is conducive to the high dispersion ofγ-Al2O3 and the increase of its lattice defects as a carrier.The synergy between ACF andγ-Al2O3 also improves the nitrogen and phosphorus removal performance of Al-ACF.The Al-ACF nitrogen and phosphorus removal system is dominated by ion exchange,and electrostatic attraction and pore adsorption also exist simultaneously.
