摘要
用石墨炉原子吸收光谱、荧光光谱法测定了不同品种香烟烟气的水吸收液中重金属的含量。并用等离子体发射光谱法进行比较测定。结果表明 ,石墨炉原子吸收光谱法具有灵敏度高、干扰小、快捷的优点。方法回收率为 97.6 7%— 10 1.18% ,相对标准偏差小于 5 .0 %。测定实际样品 。
The heavy metal elements including Pb,Cd,Cr and Hg have been determined by graphite furnace atomic absorption and atomic fluorescence spectrometry. Results of study indicate that the method of graphite furnace atomic absorption is very sensitive and easy.The recoveries of the standard addition are in the range of 97.67%—101.18%,the RSD is less than 5.0%.
