摘要
本文综述了 2011年以来国内发表的X射线荧光光谱(XRF)分析铁矿石的文献.总结了粉末压片法和熔融制样法制备试料片的条件、使用的标准试料、仪器分析条件、校准曲线评价、分析系统评价、测量不确定度评价和相关应用;展望了 X射线荧光光谱(XRF)分析在铁矿石成分分析中的应用前景;并建议开展XRF测定铁矿石主次成分用标准试料片和标准化试料片制备技术的研究和应用,以及高压粉末制样技术在铁矿石XRF分析中的应用研究工作的建议.
Abstract
In this paper,the literatures on iron ore analysis by X-ray fluorescence spectrometry(XRF)pub-lished in China since 2011 were reviewed.The preparation conditions of test portion piece,test portion for calibration curve used,the analysis conditions of instrument,the evaluation of calibration curve,the eval-uation of analysis system,the evaluation of measurement uncertainty and related applications of pressed powder pellet and fusion sample preparation are summarized.The application prospect of XRF in compo-nent analysis of iron ores was prospected.It was suggested to conduct the research and application on test portion pieces for calibration curve and test portion pieces for standardization for primary and secondary components analysis of iron ore by XRF.Moreover,the application of high-pressure powder pelleting preparation technique in XRF analysis of iron ore was also proposed.
