海水中的金属元素是海洋生态系统的重要组成部分,其形态变化会影响其在海洋中的化学行为和生物行为,因此对海水金属元素进行精确分析测定(包括对海水金属元素样品的采集、处理和测定)是十分必要的。在海水金属元素的分析测定中,原子光谱法、色谱分析法、毛细管电泳法、电化学法、质谱分析法和流动注射分析技术应用较为广泛;近年来多种仪器联用技术发展迅速,并在海水金属元素样品分析中具有广阔前景。
Metal elements are important components of marine ecosystem,and the speciation of marine metals can affect their chemical behavior and biologic behavior.Therefore it’ s quite neces-sary to determine and analyse metal elements in seawater,including sampling,sample treatment and determination.Atomic spectrometry,chromatography,capillary electrophoresis,electro-ana-lytical methods,mass spectrometry and flow injection technique have been widely applied in deter-mination of marine metals.Recently,multiple instruments hyphenated technology has been devel-oped rapidly and has a vast foreground in the field of analyzing marine metal samples.
