卡尔曼滤波同时pH配位滴定法研究

A study on simultaneous pH complexometry of Kalman filter

将卡尔曼滤波 ( KF)递推算法 ,用于多组分同时 p H配位滴定中 ,同时测定了镍矿中镍 ,铜 ,钴含量 ,讨论了方法原理 ,指定 p H值的选择 ,对 8个矿样和模拟样 ,进行了多次测定 。

Kalman Filter(KF) used as a chemometrics filter can filter out the interferences from each other.KF was applied to pH complexometry,simultanously determines Ni, Cu, Co contents in nickel minerals.The principle of this method and selection of appointed pH were discussed.Eight simultated samples and mineral samples are determined and satisfactory results are obtained.
