为拓展活性炭的资源化利用，以过50目的活性炭作为载体，硫酸亚铁为铁源，采用液相还原法制备活性炭-纳米铁复合材料。用XRD对其进行结构表征，并就其对模拟的含镍废水进行还原去除研究。实验结果表明：m（活性炭）∶m（硫酸亚铁）为1∶2所制备的活性炭-纳米铁复合材料负载的粒子主要是α-Fe，具有较强的还原性，对含镍废水具有较好的去除作用，可在重金属废水处理中推广使用。

To enhance the utilization of activated carbon, activated carbon-nano iron composites were prepared by liquid phase reduction method with ferrous sulfate as the iron source while 50 mesh activated carbon as the support. The obtained composites were characterized by XRD, and the removing processes of nickel wastewater were studied. The experimental results indicate that the activated carbon-nano iron composite which was prepared with mass ratio of activated carbon and ferrous sulfate was 1∶2 has the strong reducibility due toα-Fe,∶and has better adsorptive ability in the removal of nickel ions, which can be used in the treatment of heavy metal wastewater.
