Abstract:Hydrofluoric acid and perchloric acid are used to decompose samples,leached with nitric acid.We determine the lithium content in rocks by inductively coupled plasma atomic emission spectrometry.Measurement rangeω(Li)is 0.10%—10.0%.In this paper,the method of determination of lithium in rock and ore by inductively coupled plasma atomic emission spectrometry(ICP-AES)is established by comparing the effect of different mixed acid dissolving samples,exploring the instrument conditions and interference experiments of coexisting elements,which can fully meet the test work of lithium in rock and ore.The recovery of lithium is 98.9%—105%(n=3)by standard addition recovery experiment.The result is consistent with the standard value by the analysis of certified reference materials.This method is accurate and simple,and is suitable for the determination of lithium in rock and ore.
Keywords:rock and ore  inductively coupled plasma atomic emission spectrometry  lithium
