Abstract
A square-root Kalman filter combined with spectrometry has been applie d to determining the concentrations of vitamin B-1, vitamin B-2, vitam in B-6 and nicotinamide in synthetic mixtures and in a commercial comp osite vitamin B tablet. A simultaneous assay of the components in synt hetic mixtures containing the above mentioned four B-complex vitamins was successfully achieved with satisfactory recoveries of 97.0 - 103.3 %. The components in a commercial composite vitamin B tablet were dete rmined simultaneously, and the obtained results are in good agreement with the labeled contents of the tablet.
