海水中的铜是海洋生物的一种营养要素。测定海水中的铜含量,不仅为海洋调查所重视,且为与海洋有关的其他学科的研究工作所需的资料。海水中含铜量甚微,直接测定有困难,在分析上多采用预先浓集的方法,然后进行测定。浓集的方法有电解沉积法、共沉淀法、离子交换法和萃取法等。测定的方法以光度分析法较为广泛,光谱分析法和 Copper in seawater is a nutrient element of marine life. Determination of copper in seawater is not only important for marine surveys, but also for the research work in other marine-related disciplines. There is very little amount of copper in seawater, so it is difficult to measure directly. In the analysis, we use preconcentration method and then measure. Concentrated methods are electrolytic deposition, coprecipitation, ion exchange and extraction methods. Determination of the method to photometric analysis is more extensive, spectral analysis and methods
