摘　　要：Micro-scale Al-Zn-Mg/Fe composite powders (MAF) with high reactivity and good storage properties were prepared by reducing iron onto the surface of Al-Zn-Mg alloy powders. Experimental results show that MAF as advanced zero-valent iron are highly effective for degradation of chlorinated organic compounds. The efficiency of degradation for carbon tetrachloride and perchloroethylene is higher than 99% within a period of 2 h. The efficiency of degradation for trichloroethylene by MAF after storing for one month is equivalent to that by freshly prepared nano-size zero-valent iron particles.Micro-scale Al-Zn-Mg/Fe composite powders (MAF) with high reactivity and goodstorage properties were prepared by reducing iron onto the surface of Al-Zn-Mg alloy powders.Experimental results show that MAF as advanced zero-valent iron are highly effective for degradationof chlorinated organic compounds.
