脉冲进样火焰原子吸收法测定矿石中钾和钠

Pulsed Sampling Method for the Determination of Sodium and Potassium in Ores by Flame Atomic Absorption Spectrometry

摘要: 采用一种新的脉冲进样装置火焰原子吸收法测定了矿石中Na和K,装置也可常规进样,同时获得两种进样的分析结果。性能比较表明,脉冲进样法的耗样量、分析速度和精密度优于常规进样法。

Abstract: In this paper, a new pulsed sampling apparatus is described that can be used to determine Na and K in ores by flame atomic absorption spectrome-try. The apparatus can also be used for the conventional technique. Compared with the latter method, the pulsed
