种用于处理染料废水的Fe掺杂核桃壳活性炭及其制备方法和应用，该Fe掺杂核桃壳活性炭是以核桃壳为原料，经酸液处理、无机盐处理、热解处理、活化处理和高温热处理制备得到的。该Fe掺杂核桃壳活性炭中Fe含量分别为2.15％(wt％)，比表面积为1779.31m/g，对亚甲基蓝的最大吸附量为531.08mg/g，对其他染料包括甲基橙、孔雀石绿、甲基红的吸附量也分别超过500mg/g。本发明的Fe掺杂核桃壳活性炭吸附能力强，吸附速率快，易于回收再生，可重复使用，大大节省了处理成本。同时，本发明的方法，以废弃核桃壳为原料，操作简便，成本低廉，不会造成二次污染，实现了对农业废弃物的资源化利用。 The invention discloses Fe-doped walnut shell activated carbon for treating dye wastewater as well as a preparation method and an application of the activated carbon. The Fe-doped walnut shell activated carbon takes walnut shells as a raw material and is prepared through acid solution treatment, inorganic salt treatment, pyrolysis treatment, activating treatment and high-temperature heat treatment. The Fe-doped walnut shell activated carbon has the Fe content of 2.15%(wt%), the specific surface area of 1779.31 m /g, the maximum adsorption of 531.08 mg/g for methylene blue as well as the adsorption exceeding 500 mg/g for other dyes including methyl orange, malachite green and methyl red. The Fe-doped walnut shell activated
