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.
