A New Pulse Sampling Method For Determination of Sodium and Potassium in Feldspar by AAS

本文报导了一种新的脉冲进样装置,用于钾长石中钾钠的测定,对两种进样方法的性能进行了比较。

In this paper a new pulse sampling apparatus is employed. It can be used to determine Na and K in feldspar by flame atomic absorption spectrophotometry. The experiments showed a satisfactory analytical results of two ways sampling method were simultaneously obtained. The linear scope is 1—2 time wider than the conventional way. The analytical speed, the precision and the sampling volume are all superior than conventional way, except for sensitivity and detection limit.
