Abstract

Spectrophotometric determination of hydrogen peroxide was accomplished with osmium(VIII) and m-carboxyphenylfluorone (MCPF) in the presence of cetyltrimethylammonium chloride (CTAC). In the determination of hydrogen peroxide based on the fading of the color of osmium(VIII)-MCPF complex, Beer's law was obeyed in the range 20-406 ng mL-1, with an effective molar absorption coefficient (at 580 nm) of 5.21 × 104 L mol -1 cm-1 and a relative standard deviation of 0.33% (n = 6). Further, we performed the characterization of MCPF and obtained the crystal structure.
