    摘要: 本研究是探討不同金屬離子Fe2+與Cu2+、腐植酸與起始pH 值對微米級零價
    鐵(Fe0)還原處理水中硝酸鹽氮的影響。實驗結果發現在未控制pH 下,分別添加
    1.0 mM Fe2+和Cu2+時,還原處理硝酸鹽氮效果明顯高於未添加金屬離子。而控制
    pH 下,有無添加Fe2+並沒有顯著的影響,而添加Cu2+則有較顯著的影響。添加腐
    植酸於溶液中雖會增加微米級零價鐵的還原能力,但是其效果並不顯著。從本研
    究探討的控制因素中發現,影響微米級零價鐵對硝酸鹽去除效果之主要因素為起
    始pH 值的控制。
    The aim of this study is to explore the effects of both humic acid and different
    metal ions (Fe2+ and Cu2+) on the reduction of nitrate under different initial pH. Results
    indicate that the removal of nitrate could be enhanced by dosing Fe2+ or Cu2+ under
    uncontrolling initial pH. However, the dosing of Cu2+ could be more helpful than the
    dosing of Fe2+ in removal of nitrate. The dosing of humic acid have no significant
    efficiency on the removal of nitrate. The main controlled facter for the removal of
    nitrate with microscale zero-valent iron was initial pH of solution.
