摘要
研究了稀土元素与对溴偶氮胂的显色反应,提出了用Kalman滤波分光光度法同时测定稀土元素的方法,用于铝合金中铈组稀土元素测定,结果满意.
In pH4.5 buffer solution the rare earth elements(RE) form blue complexes with .p-brooio-arsen-azo. The simultaneous spectrophotometric determination of La, Ce, Pr and Nd with Kalman filter has been described. The proposed method was applied to determine these elements in the aluminium alloy sample .
