| Abstract: | A steady pH gradient in a flow injection system was established. Lead .vanadium and copper were simultaneously determined in mixtures by collecting the absorbances of the complexes formed by metals and PAR as the chromogenic reagent within the pH gradients controlled by a microcomputer system and kalman filter method was used to analyze the complex absorbances with satisfactory results. |
