摘　　要：为提升羊毛活性炭的吸附脱色能力,利用Fe(NO3)3、Cu(NO3)2作浸渍液制备了负载不同种类金属氧化物的羊毛活性炭,借助扫描电子显微镜、透射电子显微镜、X射线衍射及比表面积实验表征负载金属氧化物羊毛活性炭的负载效果,利用紫外分光光度计分析羊毛活性炭负载氧化物对模拟染料废水的吸附特性,然后探索分析负载工艺对负载铁氧化物羊毛活性炭吸附性能的影响规律。研究结果表明:羊毛负载氧化铁和氧化铜活性炭能很好地提升羊毛活性炭的吸附脱色效果,羊毛活性炭负载铁氧化物比负载铜氧化物的吸附脱色效果好;浸渍液Fe(NO3)3浓度为0.2~0.25 mol/L,负载煅烧时间为2 h,煅烧温度为400℃时,负载铁氧化物羊毛活性炭的吸附脱色率最好。In order to improve the adsorption decoloring capacity of wool activated carbon, Fe （ NO3 ） 3 and Cu（ NO3 ）2 were used as dipping solution to prepare wool activated carbon which was loaded with different kinds of metal oxides. The loading effect of metal oxide loaded wool activated carbon was analyzed by scanning electron microscopy, transmission electron microscopy, X-ray diffraction and specific surface area experiment. The influences of adsorption properties upon the wool activated carbon were studied by ultraviolet-visible spectrophotomery. The results show that the adsorption and decoloring effect of wool activated carbon can be improved by the loaded oxide, and the effect of iron oxide is better than that of copper oxide. The optimum process parameters are as follows： Fe（NO3 ）3 of 0.2 -0.25 naol/L, load calcination time of 2 h and load calcination temperature of 400 ℃.
