Cr<sup>6+</sup>污染对菱叶中矿质元素含量的影响

Cr⁶⁺污染对菱叶中矿质元素含量的影响

摘要: 研究Cr⁶⁺污染后菱浮水叶和沉水叶中Cr、K、Mg、Fe、Mn、Zn、Cu、Mo元素的含量, 结果显示: Cr含量随培养浓度的上升而上升, K、Mg随培养浓度的上升而下降, Fe含量随培养浓度的上升而出现先上升后下降, Mn、Zn、Cu、Mo与Cr⁶⁺的培养浓度无明显的相关关系。

Abstract: This article mainly deals with Cr's pollution affecting the content of Cr, K, Mg, Fe, Mn, Zn, Cu, Mo in floating and underwater leaves of Trapa bispinosa.The results showed the content of Cr increased with the raising cultural concentration, the contents of K, Mg decreased with the raising cultural concentration, the content of Fe increased at low cultural concentration but decreased at high cultural concentration, the contents of Mn, Zn, Cu, Mo have no correlation with Cr's cultural concentration.
