摘　　要：以高能球磨法制备了纳米尺度的单质铁粒子,并用原子力显微镜对其进行了表征.以所制备的纳米铁为处理剂,进行了去除模拟水样和地表水COD的实验,主要研究了COD去除效果与纳米铁加入量的关系.结果表明:此超细铁粉对多数水样的COD均有较好的降低效果.Zero- valent iron nanoparticles were prepared by high-energy ball milling technique and characterized by AFM, ect. Such iron nanoparticles were used as a treatment agent in the experiment of removing COD in modeling water and ground surface water. The relationship between the dosage of nanoscale iron particles and the efficiency of COD removal, indicated that the iron powders were powerful in treating pollute water.
