【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。更多还原

【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.更多还原
