摘要
建立了一种准确度高,操作简便的铌钽矿物中铌钽含量的熔片X射线荧光光谱分析法。设计制备了标准样品,对仪器参数、稀释比等条件进行了优化,对干扰元素进行了谱线重叠校正和吸收增强校正。十次测量结果表明,Nb2O5相对标准偏差0.86%,Ta2O5相对标准偏差0.58%。对实际样品进行测定,测定结果与ICP法及化学法结果一致。
A new method for determination of niobium and tantalum in ore sample by fusion beads XRF was developed. The method＇s advantage is high precision and easy operation. Standard sample, was prepared made the choice of instrument＇ s working condition and dilution ratio, adopted different matrix correction mode. Under the best working condition, ten times determination was done. The result is that the RSD of Nb2 O5 is 0. 86%, and Ta205 is 0. 58%. Analysis result of sample is in accordance with ICP and chemical method.
