介绍了应用ICP-AES法同时测定铁矿石中SiO2,MnO,CaO,MgO,TiO2,Al2O3和P七个元素的方法,首先选择溶样试剂和分析谱线,再进行仪器分析参数的设置和优化,结果直接使用标准样品制作工作曲线表示。方法中SiO2,MnO,CaO,MgO,Al2O3,TiO2,P的检出限分别为0.15,0.005,0.16,0.04,0.06,0.004,0.19μg/mL,相对标准偏差小于5.0%,基本上满足了铁矿石中该七个元素测定的要求,与标准样品对照,结果令人满意。
The method for simultaneous determination of seven elements of SiO2, MnO, CaO, MgO, TiO2, Al2O3 and P in iron ore by ICP-AES is introduced. Firstly, the sample preparation reagent and the analysis line are selected, and then the parameters of instrument analysis are set. Optimization, the results of direct use of standard sample production curve representation. The detection limits of SiO2, MnO, CaO, MgO, Al2O3, TiO2, P were 0.15,0.005,0.16,0.04,0.06,0.004,0.19μg / mL respectively, the relative standard deviation was less than 5.0% The requirements for the determination of the seven elements in the ore are compared with the standard samples and the results are satisfactory.
