Abstract: Aprocedure was established for the determination of micro Os (Ⅷ) in the anode mud by flow injection analysis-integrated microconduit made by ourselves.This metnod is based on the velocity of γ-acid oxided by oxygen in air to form quinone(red) and the reaction is catalyzed by Os(Ⅷ).The proposed method is rapid, simple and low reagent consumption.The limit of detection for Os (Ⅷ) is 0.010 μg/mLand relative standard deviation is 2.1% in the concentration range of 0.010-0.100 μg/mL.Sampling frequency is 20 times per hour.

Key words: Flow injection analysis, Osmium, Anode mud
