南极海水中超痕量金属离子的测定采用了不同的方法，并进行了严格的比较。所研究的金属离子为Cd、铜、铁、锰、镍和锌。用吸附阴极溶出伏安法和石墨炉原子吸收光谱仪对海水样品进行了分析。采用紫外光照射、酸化、在线样品富集等不同处理方法，对不同采样点和垂直剖面上的样品采集结果进行了讨论和比较。
Different procedures for the determination of ultratrace metal ions in Antarctic sea water have been adopted and critically compared. The investigated metal ions were Cd, Cu, Fe, Mn, Ni and Zn. Sea water samples were analysed with adsorptive cathodic stripping voltammetry and with graphite furnace atomic absorption spectroscopy. Different treatments, 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.
