%X Dechlorination of atrazine under acidic conditions was studied by using Fe and Ni/Fe bimetallic particles respectively for the confirmation of the catalytic role of Ni/Fe. Effect of pH value, Ni/Fe proportion and dosage of metal powder were discussed as well. The results indicated that Ni/Fe bimetallic particles was very effective for dechlorination of atrazine, with the dechlorination efficiencies above 90% by using 1.22%(W/W) Ni/Fe at pH value of 2.0 in 30 minutes, very superior to Fe particle with the dechlorination efficiencies only 22.21% in 90 minutes under the same conditions. By the comparison of the surface morphology of both Fe and Ni/Fe and experimental results, catalytic mechanism of Ni/Fe bimetallic particles was also proposed.
