摘要
Abstract
13 impurity elements of Ni,Co,Mn,K,Ca,Mg,Al,Cu,Fe,Pb,Zn,Cr,Na in Li2Tl4O12 were determined by ICP-AES.The method for dissolving sample,instrument parameters,spectra of analyzed element were compared,and interference of Ti and Li and background correction and instrument parameters was studied.Ultimately the best experimental conditions were determined.The sample was prepared by HF-H2SO4.HF was removed by heating,and the acidity of sulfuric acid was controlled between2.5％ ～ 5.0％.The standard recoveries are from 97.40％ ～ 105.04％,and the relative standard derivation is from 0.01％ ～ 2.51％.The method is simple,accurate and rapid.关键词
