APPLICATION OF KALMAN FILTERING TO INDUCTIVELY COUPLED PLASMA ATOMIC EMISSION SPECYROMETRY Ⅰ. DETERMINATION OF 14 RARE EARTHS IN HIGH PURITY THULIUM OXIDE

本文研究了电感耦合等离子体原子发射光谱分析Ｋａｌｍａｎ滤波法测定高纯氧化铥中的１４种其他稀土杂质的方法。Ｋａｌｍａｎ滤波法有效地消除光谱干扰，可利用受干扰的光谱灵敏线，因而可提高灵敏度，是一种在大量基体存在下测定痕量杂质的有效方法。

The present paper describes the application of Kalman filtering to inductively coupled plasma atomic emission spectrometry. This particular title reports the determination of 14 rare earths in high purity thulium oxide. Kalman filtering may effectively remove spectral interferences. It allows the use of sensetive spectreal lines with interferences and may increase sensetivity and accuracy
