Different procedures for the determination of ultratrace metal ions in
Antarctic sea water have been adopted and critically compared. The in
vestigated metal ions were Cd, Cu, Fe, Mn, Ni and Zn. Sea water sample
s were analysed with adsorptive cathodic stripping voltammetry and wit
h graphite furnace atomic absorption spectroscopy. Different treatment
s, such as UV irradiation, acidification and on-line sample enrichment
were adopted and the results for samples collected in different sites
and on a vertical profile were discussed and compared.
