Different species of trace heavy metals (HMs) in seawater samples were simultaneously analyzed by anodic stripping voltammetric method, an analytical technique that does not require sample pre-concentration or the addition of reagents. The effects of the crucial parameters, deposition potential and time, on the determination of HMs were investigated. Concentrations of the total dissolved, dissolved active, and dissolved inert HMs were obtained through different analysis processes. The three species of Cu, Pb, Cd and Zn in seawater samples collected in different locations across Sishili Bay, North Yellow Sea, China were studied. The relative concentration of the dissolved active Cu, Pb, Cd and Zn in the total dissolved concentrations is 59.0%, 69.6%, 87.3% and 84.1%, respectively. The concentrations of different HMs species in Sishili Bay could be affected by the discharged effluent, sea current, and uptake of marine organism.
采用阳极溶出伏安法同时分析海水样品中不同种类的痕量重金属（HMs），该分析技术无需样品预浓缩或添加试剂。研究了关键参数沉积电位和时间对痕量重金属测定的影响。通过不同的分析过程获得了总溶解态、溶解活性态和溶解惰性态痕量重金属的浓度。对中国北黄海四十里湾不同地点采集的海水样品中的铜、铅、镉和锌这三种元素进行了研究。溶解活性态铜、铅、镉和锌在总溶解态浓度中的相对浓度分别为59.0%、69.6%、87.3%和84.1%。四十里湾中不同种类痕量重金属的浓度可能受到排放污水、海流和海洋生物摄取的影响。
