使用加热石墨炉的原子吸收光谱法的仪器技术的最新进展现在使得在消除主要离子时从小体积（50-200 mL）海水浓缩后分析许多痕量金属成为可能。共沉淀与氢氧化铁需要很少的试剂和最小的样品操作，这表明它的使用作为一个常规的海水分析的预浓缩程序。沿着叙述了用中子活化或原子吸收光谱法从少量海水中分离铝、铅和钒的方法。18篇参考文献，3个表格。
Recent advances in instrumentation technology for atomic absorption spectrometry using the heated graphite furnace now make it possible to analyze for many trace metals after concentration from small volumes (50-200 mL) of seawater when the major ions are eliminated. Coprecipitation with ferric hydroxide requires few reagents and minimal sample manipulation, suggesting its use as a routine preconcentration procedure for the analysis of seawater. The separation of Al, Pb, and V from small volumes of seawater is described along with analysis by neutron activation or atomatic absorption spectrometry. 18 references, 3 tables.
