A Method for the Analysis of Rare Earth Elements in Natural Waters by Isotope Dilution Mass Spectrometry.

Abstract

A method is described to measure rare-earth elements (REE) in natural water samples. An iron hydroxide precipitation followed by ion exchange chromatography is used to concentrate and separate the REE from other matrix components. Additionally, the rare-earth elements themselves are separated into three fractions using an organic acid with a second cation column. Instrumental detection is by isotope dilution mass spectrometry (IDMS) using either thermal ionization mass spectrometry (TIMS) or inductively coupled plasma-mass spectrometry (ICP- MS). Excellent precision is shown by many duplicate and replicate analyses. Blanks are 1-2% or less of samples. (AN)
