Abstract: A novel design has been constructing and modulating of Spectroinc 20 to measure the chemiluminescence by the home- made semi-automated flow injection system. The proposed method was direct, simple and rapid for determining Hydrogen peroxide in the rang 3.3-106 gml-1 based on chemiluminescence by oxidation with luminol in aqueous sodium carbonate (PH 10). The detection limit (3noice) of 1.6 gml-1, the r. s. d % for fife determination of 26.5 gml-1 Hydrogen peroxide was 0.35 %. . The applicability of the method was demonstrated by the determination of Hydrogen peroxide in pharmaceutical formulations.
