A method has been developed for the analysis of cobalt in natural waters by cation-exchange liquid chromatography using chemiluminescence detection. Cobalt can be determined directly in freshwater samples on 500-..mu..L samples with a detection limit of 20 pmol/kg; larger samples provide proportionately lower detection limits. Seawater samples can be analyzed on 100-mL samples following APDC solvent extraction; the detection limit of this method is 5 pmol/kg. The precision of the method is +/- 5%. The method should also be applicable to the analysis of V, Cu, and Fe in natural waters. Equipment is low in cost and transportable and can be used in the field.
