研究了火焰原子吸收分析的微量溶液脉冲雾化技术及某些因素对测定灵敏度、精密度、检出限的影响。结果表明脉冲雾化和常规连续雾化火焰原子吸收测定灵敏度、检出限和精密度以及校准曲线的线性浓度范围基本一致。将脉冲雾化技术用于低合金钢标样、工业纯硅、金属锂、褐煤矿中某些元素的火焰原子吸收测定获得了满意的结果。
The effects of pulse atomization technique and some factors on determination sensitivity, precision and detection limit of flame atomic absorption spectrometry were studied. The results show that the sensitivity, the detection limit and the precision of the flame atomic absorption spectrometry and the continuous continuous atomization flame atomic absorption spectrometry are basically the same as the linear concentration range of the calibration curve. The results of flame atomic absorption spectrometry (FAAS) of pulsed atomization technology for low alloyed steel samples, industrial pure silicon, metallic lithium and lignite ore obtained satisfactory results.
