On Chemical Equilibrium by Kalman Filtering Spectrometry

Abstract

Abstract: New methods based on the combination of spectrometry with Kalman filtering (KF) and factor analysis (FA) are proposed for investigation of chemical equilibria. Complex chemical equilibria are considered as special mixture systems with multicomponent in which there exist mutual equilibria among species in various media. Kalman filtering and factor analysis are used as an effective chemo-metrics resolution tool to extract the information from the spectral data. The number and concentrations of the existing species and the equilibrium constants between base and acid are estimated for some triphenylmethane (triaromylmethane) indicators or reagents.

Key words: Chemical, equilibrium, Triphenylmethane (triaromylmethane) reagents, Acid-base equilibrium, Chemometrics, Kalman filtering spectrometry
