Very low concentration of Co, Cu, Cd, Ba, Mn, Ni, Pb in water samples at Larsemann Hills and East Antarctic was determined by off line preconentration with chelating cation exchange resin D401 coupled with ICP MS.

• 采用脱线螯合阳离子树脂 (D40 1 )将待分析元素预富集并与基体元素分离 ,采用电感耦合等离子体质谱法 (ICP MS)测定了南极拉斯曼丘陵地区环境水样中的难于或不能直接检测的超痕量元素Mn ,Co ,Ni,Cu ,Cd ,Ba和Pb ;
