卡尔曼滤波同时pH滴定法研究

A study on simultaneous pH titration of Kalman filter

将卡尔曼滤波(KF)递推算法,用于多组分同时pH滴定中,讨论了方法原理,pH通道的选择,同时对二、三、四元系统混合酸(碱)试样,进行了多次测定,获得满意结果.

Kalman filter (KF) used as a chemometrics filter can filter out the interferences from each other.KF pH titration was applied to simultaneous determination of the mixture of acids or bases.The principle of this method and selection of pH channel have been discussed.10 of mixed samples of acids or bases have been determinated with satisfactory results.
