中文摘要 | 為篩選出重金屬離子吸附能力較佳之外來入侵種植物,以作為汙染廢水之淨化,提升自然水資源之安全性,本研究採集小花蔓澤蘭、布袋蓮、含樹皮銀合歡與不含樹皮之銀合歡等四種試材。試材經磨粉機打粉後,篩選出40~60 mesh粉末作為試驗之材料,並與Cu(II)、Pb(II)、Cd(II)及Ni(II)等四種重金屬離子標準溶液進行吸附試驗。試材與重金屬離子溶液以不同質量、振盪時間與pH值處理後,將過濾之濾液以感應耦合電漿原子發射光譜儀(Inductively coupled plasmaatomic emission spectroscopy,ICP-AES)進行分析比較其對重金屬離子之吸附效果。試驗結果顯示,相同質量0.4 g之四種試材對於重金屬離子吸附效果為:小花蔓澤蘭對於Cu(II)、Pb(II)及Cd(II)等離子溶液之吸附效果較佳,而布袋蓮、含樹皮銀合歡與不含樹皮銀合歡之吸附效果則以Pb(II)離子溶液較佳;改變振盪時間對於四種試材之重金屬離子吸附效果差異並不明顯;在相同pH=6的情況下,比較四種試材對重金屬離子吸附效果為:含樹皮銀合歡>布袋蓮>小花蔓澤蘭>不含樹皮之銀合歡;四種重金屬離子之移除效果依序為Pb(II)>Cd(II)>Cu(II)>Ni(II)。 |
英文摘要 | adsorptive efficiency of specimens for removing heavy metal ion was evaluated with different mass weight, vibration times and pH values by immersing specimen into the standard heavy metal ion aqueous solutions of Cu (II), Pb (II), Cd (II) and Ni (II). The filtrates from the treated solution were further analyzed by inductively coupled plasma emission spectroscopy (ICP-AES). The experimental results revealed that better heavy metal ions adsorptive efficiency in M. micrantha, based on the mass weight of 0.4 g, was observed in specimen treating with Cu (II), Pb (II), and Cd (II) aqueous solutions. Meanwhile, better result was obtained when treating E. crassipes, L. glauca and debarked L. glauca specimens with Pb (II) aqueous solution. No significant difference was observed in the heavy metal ions adsorptive efficiency at different vibration times. Among four specimens, the heavy metal ions adsorptive efficiency was in the order of L. glauca > E. crassipes > M. micranth > debarked L. glauca when the solution treatment of pH was at 6, and the amounts of heavy metal ion removal was in the order of Pb (II) > Cd (II) > Cu (II) > Ni (II). |
