Abstract: The proper color-reaction condition of dibormocarboxyarsenazo with thorium (Ⅳ) are discussed.With the Kalman filter-spectrophotometry, thorium and lanthanum in waste water have been simultaneously determined by using the chromogenic reagent dibormocarboxyarsenazo with satisfactory-results.The average recovery of thorium and lanthanum are 100.68% and 99.62% respectively, the average deviation of determined results are less than +4.0%, and both with good reproducibility.

Key words: Kalman filter-spectrophotometry, Dibormocarboxyarsenazo, Thorium, Lanthanum, Simultaneous determination of multicomponent
