【摘要】 利用电感耦合等离子体质谱(ICP-MS)研究了胶州湾及莱州湾这两个海域中痕量元素污染水平,发展了ICP-MS海水环境中痕量元素的测定方法,同时找出海水环境中具有保守性的数种元素作为污染示踪元素。达到对于海水环境中痕量污染物被动示踪的目的。对18个真实样品进行了识别率试验,识别率可达90%以上,在选取3个海水样品及1个河水样品混合后的模拟分担率实验,也取得了满意的结果,其误差平均值仅有1.17%。更多还原

【Abstract】 Inductively coupled plasma-mass spectrometry(ICP-MS) was developed into an accurate and sensitive technique for the multi-element determinations in a range of sample matrices.The seawater samples in Lai zhou Bay and Jiaozhou Bay as a case was studied.The distribution of trace elements in seawater can be used in the source fingerprints for the identification of seawater samples from different locations.The probability of success for the source identification by the technique is better than 90%.The feasibility of trace metals in seawater as a tracer for the tracking of pollution sources has been evaluated.Combined with the chemo-metric analysis,3 seawater and 1 river samples were mixed,the error is only 1.17%.更多还原
