    Abstract: 本研究目的是以一起合成與分開合成不同鐵鎳配比之鐵鎳雙金屬對於硝酸鹽進行處理,探討其有控制酸與未控制酸條件下對於鐵鎳雙金屬去除硝酸鹽的影響。在實驗中發現鐵鎳雙金屬對硝酸鹽處理的效果會比單一金屬要好,推測可能是因為鎳扮演催化的角色,促進鐵的還原能力。並且在pH越低的情況下效果越佳,原因可能是在酸性條件下有利於金屬表面的活化,使金屬表面處於有效表面狀態,使效果越好。
    The aim of this study is to compare the effects of nanoscale Fe0-Ni0 bimetallics synthesized simultaneously with synthesized separately on the treatment of nitrate as well as to explore the effects of pH on the reduction of nitrate. Results indicate that nanoscale Fe0-Ni0 bimetallics performed better than Fe0 or Ni0 alone. This might be due to the catalysis of Ni0 to promote the reduction ability of Fe0 on nitrate. Higher reduction of nitrate was found under lower pH condition, which might result from the surface availability of metal.
