建立了一种快速、可靠、省时省力的样品预富集方法，用于电感耦合等离子体质谱（ICPMS）测定海水中稀土元素。该方法包括将双（2-乙基己基）磷酸氢盐（HDEHP）和2-乙基己基磷酸二氢盐（H 2 MEHP）的混合物吸附到C18柱上。海水样品通过C18柱后，稀土元素与吸附的络合剂发生定量络合，几乎所有的基体元素都通过柱进入排放管
A rapid and reliable sample preconcentration method with minimum time-consumption and labor has been developed to separate rare-earth elements (REEs) from seawater for the measurement by inductively coupled plasma mass spectrometry (ICPMS). The method involves adsorption of a mixture of bis(2-ethylhexyl) hydrogen phosphate (HDEHP) and 2-ethylhexyl dihydrogen phosphate (H 2 MEHP) onto a C 18 cartridge. By passage of seawater samples through the C 18 cartridge, quantitative complexation of REEs with adsorbed complexing agent took place and almost all matrix elements passed through to the drain
