摘要
本文采用自适应卡尔曼滤波(AKF)分光光度法,分析了以5-Br-PADAP为显色剂,OP为增溶剂的Cu、Zn、Co、Ni混合体系,探讨了显色条件、滤波参数选择等问题。合成试样解析结果表明:AKF法能很好地消除由于这四个元素的络合物光谱严重重叠而致的相互干扰,获得准确的分析结果。同时因AKF法可在一定程度上校正混合体系吸光度对加和性的偏离,故而计算结果优于普通卡尔曼滤波法(KF)。
Adaptive Kalman filtering has been deevloped for the simultaneous spectrophotometric determination of Cu、Zn、Co and Ni chelating system with 5-Br-PADAP and OP.Influence of several factors on the filtering results has been studied.The results show that the recoveries of adaptive Kalman filtering are satisfactory and better than those of mormal Kalman filtering,due to the ability of adaptive Kalman filtering of automatic compensation for errors occured in measured model.
