摘要
在优化的检测流程下分析,火焰原子吸收光谱法测定铁矿石中铅锌钾钠100个样由改进前的10 h缩短至6 h。标样10次的分析结果与真值的最大偏差为0.002,相对标准偏差根据检测的含量不同分布为1.4%~13.9%,完全满足标准规定的允许差范围。
The time for determining lead, zinc, potassium and sodium in iron ore by the flame atomic absorption spectrometry is shortened from 10 hours to 6 hours when 100 samples are analyzed by the optimized detection process. The maximum deviation is 0. 002 between the analysis results and the true value of ten stand samples. Relative standard deviation according to the different content is 1.4% ~ 13.9% ,which fully meet the standard of allowable deviation.
