摘要
用原子吸收分光光度法分析了玉米根、茎、叶中重金属离子的含量.测定了锰废渣对盆栽玉米植株生长的影响,研究了电解锰废渣中重金属离子在植物体内的富集.结果表明:从株高来说,废渣种植>处理后废渣种植>土壤种植;铁离子的主要富集部位在根,最高富集量为2.347 3×10-5,镉离子的主要富集部位在叶,最高富集量为3.57×10-7,铬离子在根茎叶中的含量差不多,最高富集量为3.15×10-7;废渣种植的玉米籽中重金属离子的含量最高,其中:Mn、Zn、Fe离子的含量非常高,分别达1.0×10-5,1.6×10-5,4.0×10-6;Cr离子的含量高达3.7×10-7;Cd离子的含量高达4.0×10-8.
Using com as experimental material, and using AAS to analyze the content of heavy mental ion in the root, stem and leaf of the com, the experiments measure the influence of manganese slag on the growth of com planted in the pot,examine the accumulation of heavy mental iron in the plant. The results show that the height of the com is soil plant 〈 treated plant 〈 slag plant, the chief accumulation position of Fe iron is root, the max value is 2. 347 3 × 10^-5 ; the chief accumulation position of Cd iron is root; the max value is 3.57× 10^- 7 ; the accumulation of Cr iron in the root, stem, leaf is almost the same, and the max value is 3.15 × 10^-7. There is a max value of heavy mental iron in the com seed planted with the slag,and the max value of Mn, Zn, Fe, Cr, Cd respectively reach 1.0 × 10^-5, 1.6× 10^-5, 4.0 × 10^-6 ,3.7 × 10^-7 ,0.4 × 10^-8.
