卡尔曼滤波——分光光度法用于饮料中色素的同时测定

Simultaneous Determination of Pigments in Drinks by Kalman Filter—Spectrophotometry

卡尔曼滤波(KF)是一种基于最小二乘法原理的线性估计递归(推)算法。本文用卡尔曼滤波—分光光度法实现了饮料中的苋菜红和胭脂红的同时测定,同国家标准方法比较,不仅结果有较好的一致性,而且又避免了繁琐的色层分离操作。

Kalman filter(KF), based on the least square(LS), is a recursive algorithm used for the estimation of linear parameters. Simultaneous determination of amaranth and ponceau 4R in drinks, by using Kalman filter-speetrophotometry, is reported. The results by this method show a good agreement with those by the national standard method of China.
