title: [Empirical modeling of interference effects with flame photometric potassium and sodium determination in water analysis].
abstract: A method of empirical modelling based on experimental design by multifactor plans is adapted and applied in the determination of the interfering effects on the flame photometric analysis of potassium and sodium in waters. Basing on the obtained analytical signals and a following linear transformation calibration equations have been approximated to take into consideration the interfering effects. By means of the proposed method it is possible to increase the reliability of the flame photometric determination of potassium and sodium in water analysis.
