摘  要:
采用三步连续提取法,并用电感偶合等离子质谱(ICP-MS)和总有机碳测定仪(elementar Germany)对底泥中的重金属(Cu、Cd、Pb、Zn、Cr、Mn、Ni)总量和形态进行测定,研究了京杭大运河(徐州段)6个底泥样品中的重金属含量及形态分布和有机碳的关系。结果表明,Cr、Zn、Cu大部分是以残渣态形式存在,6点分别为80.0%~93.6%,52.7%~99.5%和62.7%~92.8%。Cd、Mn、Pb的醋酸可提取态含量很高,Ni的可氧化提取态含量高。相关性分析表明有机碳的含量与可氧化提取态的相关性较好。

摘  要:
Total content and morphological of heavy metals including Cu,Cd,Pb,Zn,Cr,Mn,Ni in six bottom sediments of Beijing-Hangzhou Grand Canal(Xuzhou section) were determined by three step continuum extraction method and by ICP-MS and TOC Elementar Germany.The result showed that Cr,Zn and Cu was in form of residual fraction,respectively being 80.0%~93.6%,52.7%~99.5% and 62.7%~92.8% in 6 sampling spots.Cd,Mn and Pb had high content of vinegar acid extractive fraction.Ni had high content of oxygenation extractive fraction.Relativity analysis indicated that the contents of total organic carbon had better relation to the oxidizable extraction fraction.
