卡尔曼滤波算法是基于数学理论发展起来的一种数字滤波算法。Poulisse和Didden首先用该法确定了在紫外、可见光谱图中重叠峰所含的组分数并获得了组分浓度值,研究表明:卡尔曼滤波算法结合分光光度法对多组分重叠峰有很强的分辨率,为药物多组分测定提供了新的、简单、快速的分析手段。本文用卡尔曼滤波分光光度法测定了安钠咖注射液 Kalman filter algorithm is based on mathematical theory developed a digital filtering algorithm. Poulisse and Didden first used this method to determine the number of components contained in the overlapping peaks in the ultraviolet and visible spectra and obtained the component concentration values. The results show that the Kalman filter algorithm combined with spectrophotometry has the advantages of multiple component overlapping peaks Strong resolution provides a new, simple, and rapid means of analysis for multi-component assays. In this paper, Kalman filter spectrophotometric determination of sodium injection
