【摘要】 通过膜过滤(0.45μ),紫外光照射和螯合树脂(Chelex-100)处理,再应用微分脉冲极谱阳极溶出伏安法测定第二松花江源头区、上、中、下游17个采样点江水中铜、铅、镉、锌的十种形态.按不同江段对各金属的总量、悬浮态和溶解态所包含的七种化学形态的分配比进行综合分析,阐述了主要存在形态和各形态的相互转化及迁移规律.更多还原

【Abstract】 By using membrane filtration (0.45μ), ultraviolet irradiation and chelating resins (Chelex-100), and then application of DPASV, observation of 10 forms of copper, lead, cadmium and zinc was done from the seventeen sampling stations along the upper, middle and lower reaches of the Second Songhua River. For different riversections, a comprehensive analysis was made to show distribution ratio of the seven chemical forms which include the total quantity, the suspended state and the dissolved state. As a result it extends to explain the pattern of mutual change and transformation between the main existing and other forms.更多还原
