摘　　要：采用溶胶凝胶法在活性炭纤维(Active Fiber Carbon,ACF)上负载TiO2,制备出TiO2/ACF复合材料,考察了对咖啡因制备中间体ANDMU光催化氧化行为,结果表明负载TiO2后的ACF对ANDMU的吸附有所减弱,但在紫外光照射下,ANDMU的浓度可以进一步降低,说明TiO2/ACF对ANDMU具有一定的光催化氧化效果,对于制备咖啡因的工业水处理提供了有益思路。TiO2/Active carbon fiber(TiO2/ACF)composite material was prepared with loading TiO2 on ACF by a sol-gel method.The photocatalytic activity of TiO2/ACF was assessed by degradation of 6-amino-5-ni-troso-1,3-dimethyluracil(ANDMU),a important chemical intermediate in caffeine industry.Our results show that TiO2/ACF adsorbed the less amounts of ANDMU than that of ACF,because of the decrease of specific surface area after loading TiO2.However,the concentration of ANDMU decreased further by adsorption and photocatalytic degradation of TiO2/ACF under UV light irritation,showing some potential of application in the treatment of effluent in caffeine industry.
