METHOD OF ANALYZING THE ISOTOPE OF LITHIUM, CAPABLE OF CONVENIENTLY AND RAPIDLY PERFORMING ALL PROCEDURES COMPRISING THE PRE-PROCESSING OF SAMPLE, THE SEPARATION AND RECOVERY OF LITHIUM AND THE ANALYSIS OF THE ISOTOPE OF LITHIUM

摘要

PURPOSE: A method of analyzing the isotope of lithium is provided to enable the isotope of lithium to be accurately analyzed using an inductively-coupled plasma spectrometer.;CONSTITUTION: A method of analyzing the isotope of lithium is as follows. After drying a seawater sample or a dissolved rock sample, the mixed solution of nitric acid with methanol is poured to change a medium. The medium changed sample passes a cation exchange resin column. After passing the cation exchange resin column, the mixed solution of nitric acid with methanol separates lithium from other element. Lithium separated solution is analyzed using an inductively-coupled plasma mass spectrometer in a static mode. The lithium is separated from other element in a section between 7ml~18ml.;COPYRIGHT KIPO 2011
