[Kalman filtering-titrimetry: potentiometric titration of benzalkonium bromide].
The application of Kalman filtering and smoothing to titrimetry has been investigated. The method is suitable for titration systems in both thermodynamic equilibrium and non-equilibrium (dynamic). Particularly, Kalman filtering and smoothing can give correct results in cases when other traditional methods failed. The effect of model noise, titration rate and sampling time was also examined on the accuracy of the filtering titrimetry. The proposed method has been applied to potentiometric titration and rapid determination of benzalkonium bromide.
