摘　　要：采用一种制备简单、成本低的介孔氧化铝为吸附剂,探究了其去除水中有机农药草甘膦的性能。首先采用溶胶-凝胶法制备了具有高比表面积和大孔径的介孔氧化铝。探究了沉淀剂种类、十六烷基三甲基溴化铵(CTAB)用量及煅烧温度对介孔氧化铝吸附草甘膦的性能影响。结果表明,以碳酸氢铵为沉淀剂、CTAB和氧化铝物质的量比为0.33、煅烧温度为550℃时制备的介孔氧化铝720 min对初始质量浓度为100 mg·L^(-1)的草甘膦的吸附效果可高达85 mg·g^(-1)。该材料在处理草甘膦废水方面优于大多数金属氧化物和其他介孔材料吸附剂,说明其在处理草甘膦方面的巨大潜力。The mesoporous alumina was used as the adsorbent for effective treatment of organic pesticide glyphosate.Mesoporous alumina was synthesized using the sol-gel method.The effects of preparation conditions such as precipitator type,dosage of cetyltrimethyl ammonium bromide(CTAB)and calcination temperature on the adsorption properties of mesoporous alumina were investigated.Results demonstrated that when ammonium bicarbonate was used as a precipitator,with a molar ratio of CTAB to alumina at 0.33 and calcination temperature at 550℃,mesoporous alumina exhibited an impressive adsorption capacity for glyphosate with iniatl concentration of 100 mg·L^(-1) up to 85 mg·g^(-1) at 720 min.Compared to other reported materials,this material outperforms most metal oxides and other mesoporous materials due to its exceptional potential in glyphosate removal.
