摘要

  • 摘要: 采用连续化学提取法对杭钢纳污水系底质中铁和锰的化学形态作了分析。试验中采用了6种提取溶剂:1M乙酸铵溶液(pH7.0),1.1M乙酸-乙酸钠缓冲溶液(pH5.0),0.05MEDTA溶液(pH4.8),0.1M盐酸(pH1.0),3%过氧化氢的2.5%乙酸溶液(pH2.6),0.1M抗坏血酸溶液(pH2.4)。根据6个不同采样点底质样品的分析结果,对底质中铁和锰的化学形态分布和它们的环境化学行为作了讨论。
    Abstract: Sequential leaching experiments were carried out in. order to study chemical forms of iron and manganese in sediments cf the rever system accumulating in waste water of Hangzhou Iron p.nd Steel Works . Six leaching solutions, 1M ammonium acetate (pH7.0), 0.1 M r.cetate buffer (pH5.0) 0.05 M EDTA (pH4.8), 0.1 M chlorhydric acid (pH 1.0), 3% hydrogen peroxide in 2.5% acetic acid (pH2.6), 0.1 M ascorbic r.cid (pH2.4) were used. Based on the results obtained from the six samples of sediments, the distribution of chemical forms of iron and manganese in sediments and their environmental chemical behaviurs have been discussed.
