建立了全谱直读电感耦合等离子发射光谱法(ICP–AES),同时测定了其中卷烟烟气中钾钠离子的含量。研究了元素分析标准曲线、精准度、回收率以及不同种类烟草样品中两种离子的含量差别。结果表明,在选定的波长下测定,元素间也没有干扰.该方法快速,准确可靠,加标回收率为95~98%,相对标准偏差RSD均小于4%,适用于对卷烟主流烟气的检测。 Full-spectrum direct-reading inductively coupled plasma-atomic emission spectrometry (ICP-AES) was established, and the contents of potassium and sodium in cigarette smoke were also determined. The standard curve of elemental analysis, the precision, the recovery rate, and the differences in the contents of two ions in different types of tobacco samples were studied. The results showed that there was no interference between the elements at the selected wavelength.The method was rapid, accurate and reliable.The recoveries were 95-98% with relative standard deviations (RSDs) less than 4% The test.
