采用螯合树脂间歇法预富集近岸海水中的稀土元素，并采用电感耦合等离子体质谱（ICP-MS）同时测定。在此过程中，消除了基质成分（Na、K、Mg 和 Ca），以减少 ICP-MS 分析中的基质效应，并以 100 的浓缩倍数浓缩稀土元素。详细检查了回收率的 pH 依赖性、树脂量、用于洗涤的醋酸铵量以及用硝酸洗脱吸附金属的情况，以优化样品预处理的实验条件。采用本分析方法成功测定了沿海海水中的所有稀土元素，达到ppt或亚ppt水平。
Rare earth elements in coastal seawater were preconcentrated by using chelating resin in a batch method and determined simultaneously by inductively coupled plasma mass spectrometry (ICP-MS). In this procedure, matrix components (Na, K, Mg, and Ca) were eliminated to reduce matrix effects in ICP-MS analysis and rare earth elements were concentrated by a concentration factor of 100. The pH dependence of the recovery, resin amounts, amount of ammonium acetate for washing, and elution of adsorbed metals with nitric acid were examined in details to optimize the experimental conditions in sample pretreatment. All rare earth elements in coastal seawater were determined at the ppt or sub-ppt level successfully by the present analytical method.
