| description | This is an essay in the field of mineral analysis. The ore sample was digested with Hydrochloric acid、nitric acid、 hydrofluoric acid、 sulfuric acid in a closed polytetrafluoroethylene digestion tank. Hydrochloric acid and tartaric acid medium is used for extraction. The Lithium、Beryllium、niobium and tantalum in the prepared solution were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). The emission spectral intensity of Lithium、Beryllium、niobium and tantalum showed a good linear relationship with ρ(Li) and ρ(Be) in the range of 0~50 μg/mL、ρ(Nb2O5) and ρ(Ta2O5) in the range of 0~100 μg/mL. The correlation coefficients of the calibration curve for Lithium、Beryllium、niobium and tantalum were both 0.9999．The detection limits for Lithium、Beryllium、niobium and tantalum were 0.1 μg/g、0.5 μg/g、1.0 μg/g、0.1 μg/g, respectively．The proposed method was applied to the determination of the actual sample giving recovery rate of 94.6%~105.6% and the relative standard deviations (RSD n=11) of Lithium、Beryllium、niobium and tantalum are 1.08%~7.04%、0.65%~13.06%、2.59~7.32%、2.02%~7.60%, respectively．This method was applied to the analysis of the standard sample and the results were consistent with the certified values． |
