【摘要】 本方法讨论了在火焰原子吸收仪上分别于 Atomic Absorption 和 Emission 两种状态,用标准曲线法测定可过滤态钾和钠。得出在 Emission 状态测定钾和钠更加灵敏,加标回收率为93%～110%,相对标准偏差为<3%,避免了因灯不稳造成的基线偏移。更多还原

【Abstract】 Determination of kalium and natrium by Atomic Absorption state and emission state has been discussed in this paper.The later state has higher sensitivity than Atomic Absorption state.The recycling rate varies from 93% to 110%,the RSD obtained is less than 3%.更多还原
