研究了利用ICP-MS测定海水中痕量和超痕量元素的多元素分析方法。海水中添加铝将痕量和超痕量元素预浓缩10倍或20倍，然后通过ICP-MS进行测定。在此过程中，添加铝作为共沉淀的载体；它与海水中的镁一起沉淀。共沉淀后还通过 ICP-AES 测量了一些痕量元素。此外，用酸化水稀释后，通过ICP-AES测定海水中的主量和微量元素。结果，共可测定近岸海水中37种元素。目前的结果与开放海水中元素的浓度进行了比较。
An analytical method for multielement determination of trace and ultratrace elements in seawater has been investigated by using ICP-MS. Trace and ultratrace elements were preconcentrated by 10- or 20-times with addition of aluminum into seawater and then the elements were determined by ICP-MS. In this procedure, aluminum was added as the carrier for coprecipitation; it precipitated together with magnesium in seawater. Some trace elements were also measured by ICP-AES after coprecipitation. In addition, major and minor elements in seawater were determined by ICP-AES after dilution with acidified water. As the result, 37 elements in total could be determined in coastal seawater. The present results are compared with the concentrations of the elements in open seawater.
