LITHIUM ISOTOPE ANALYSIS IN WATERS AND SEDIMENTS
Journal Title: Biuletyn Państwowego Instytutu Geologicznego - Year 2011, Vol 444, Issue 444
Abstract
The purpose of the present study was to develop a method of lithium extraction from water solutions on a cation exchange column and to determine its isotope ratio by thermal ionization mass spectrometry. This method of lithium isotope determination requires neither complicated chemical preparation of the investigated samples, nor large quantities of material, thus being one of the simplest methods. The following samples have been investigated using this method: seawater from the Mediterranean Sea, mineral water from the Zuber I borehole in Krynica-Zdrój, and a sediment sample from this water.The values of d7Li for all the samples were achieved with reproducibility of the order of 1‰. The result obtained for seawater (32.2 ±1.9‰) falls into the range known from literature. The delta values for the Zuber I mineral water (–17.3‰) and the sediment precipitated from this water (–1.5‰) are, according to the best knowledge of the authors, published and discussed for the first time.
