摘要
采用卡尔曼滤波分光光度法同时测定了水样中的微量铁和铝。就其显色条件、加合性及滤波范围进行了探讨。此法可不经分离、掩蔽同时测定吸收光谱严重重叠的铁和铝，滤波范围为５６０～６９５ｎｍ，线性范围为铁０～１０μｇ／２５ｍｌ，铝０～６μｇ／２５ｍｌ，平均回收率铁为９７．７％，铝为９６．０％；变异系数铁８．９０％，铝８．５４％。
In this paper,simultaneous spectrophotometric determination of trace elements iron and aluminium with CAS-CTMAB chromogenic system by Kalman Filter spectrophotometric technique has been proposed .The method has applied to the analysis of water with satisfactory results.It is simple,no masking reagent or separation is necessary in the analysis.
